This happens because smoking causes inflammation around the teeth and increases your risk for bacterial infections. The gums may become swollen and bleed (gingivitis) and eventually begin to pull away from the teeth (periodontitis). Smoking also has an effect on insulin, making it more likely that you’ll develop insulin resistance. People who smoke cigarettes have a 30% to 40% greater risk of developing type 2 diabetes and its complications. Smoking can increase the risk of developing squamous cell carcinoma (skin cancer) on the lips.

Usually the explosions are caused by faulty batteries or because the batteries were not handled as they should be. Visit the Food and Drug Administration website for safety tips to help avoid an e-cigarette battery explosion. Among people who were hospitalized with severe EVALI, most were younger than 35 and used THC-containing vapes from informal sources (online, family or friends). However, EVALI can happen in anyone using either nicotine or THC-containing vapes.

Vaping works by heating liquid in a small device so you can breathe it into your lungs. The e-cigarette, vape pen or other vaping device heats the liquid in the device to create an aerosol. Mist from e-cigarettes contains particles of nicotine, flavoring and other substances suspended in air. You breathe these particles into your mouth from the mouthpiece, where they go down your throat and into your lungs. But, Blaha says, interpreting the data is tricky, since young people change their preferences often, and, when surveyed, may not consider using disposable products such as "puff bars" as vaping. The same CDC report says disposable e-cigarette use has increased 1,000% among high school students and 400% among middle school students since 2019.

Protect the environment and ensure safe disposal of e-cigarette products by discarding them properly. Vapes, e-cigarettes, refills and cartridges should be treated like hazardous waste and taken to your local hazardous waste facility or hazardous waste collection event for disposal. Always remove the device's battery before dropping off to prevent unintentional burns, fires, and explosions. Store these products safely to protect yourself and any children in and around the home from accidental exposure.

These devices are permitted on planes, but the FAA recently notified airlines that the lithium batteries used in these devices are fire hazards and should not be packed in checked baggage. This page may contain information that is outdated and may not reflect current policy or programs. But, CDC stats on teen smoking show that while use of e-cigs went up to 24% in 2015, cigarette smoking dropped to an historic low -- to just under 11%.

E-cigarettes are known by many different names, including "vapes," "e-cigs," "puff bars," and "electronic nicotine delivery systems (ENDS)." E-cigarettes are devices which produce an aerosol by heating a liquid that usually contains nicotine—the addictive drug in regular cigarettes, cigars, and other tobacco products—flavorings, and other chemicals that help to make the aerosol. Bystanders can also breathe in this aerosol when the user exhales into the air. The nicotine in e-cigarettes and regular cigarettes is highly addictive. While these devices may help some people quit smoking, there is growing evidence that e-cigarettes can pose serious health risks, especially to people who do not smoke traditional cigarettes.

To be clear, I never even used to smoke during the day when I was using cigarettes. But if a project is particularly stressful (or just slightly vexatious, any excuse will do), my sleek little e-cig is just sitting in my bag at my feet. Like a never-ending pipe, you don’t know when you’ve had enough, when you’ve had a cigarette’s worth of nicotine. One quick puff to slay your stress can turn into one puff every few minutes, then whenever I get the slightest urge.

Overall, comparisons of the particle-size distribution in aerosols from e-cigarettes found that the substances tested had particle distributions similar to the traditional e-liquids containing nicotine. "Our finding indicates that health care expenditures for a person who uses e-cigarettes are $2,024 more per year than for a person who doesn’t use any tobacco products," said lead author Yingning Wang, PhD, of the UCSF Institute for Health & Aging. Use of electronic cigarettes costs the United States $15 billion annually in health care expenditures – more than $2,000 per person a year – according to a study by researchers at the UC San Francisco School of Nursing. Between 2016 and 2022–2023, the proportion of people who both smoked regular (combustible) tobacco cigarettes and used e‑cigarettes increased, as did the proportion who currently used e‑cigarettes but did not use regular cigarettes.

However, to date, no e-cigarette product has been approved by the FDA for quitting smoking. Although e-cigarettes have been sold in the U.S. for nearly 20 years, use patterns have shifted dramatically. As newer iterations brought higher levels of nicotine in an increasing array of flavors and product designs, youth use skyrocketed.

In 2022–‍2023, 2.3% of people in Australia both smoked regular cigarettes and used e‑cigarettes, an increase from 0.7% in 2016. In the second study, researchers analyzed heart blood flow, a measure of coronary vascular function, of 19 young adult smokers immediately before and after smoking either e-cigarettes or tobacco cigarettes. They examined coronary vascular function by a myocardial contrast echocardiography while participants were at rest and after performing a handgrip exercise to simulate physiologic stress. In the first study, researchers looked at the impact of e-cigarettes on lipids and glucose in the blood. They recruited 476 healthy human participants without cardiovascular disease who were either nonsmokers, e-cigarette-only smokers, smokers of e-cigarettes and tobacco cigarettes and those who smoked tobacco cigarettes only.

Turkey, which has one of the highest percentage of smokers in its population,[126] has a legal age of 18. Japan is one of the highest tobacco-consuming nations, and requires purchasers to be 20 years of age. Since July 2008, Japan has enforced this age limit at cigarette vending machines through use of the taspo smart card. In other countries, such as Egypt, it is legal to use and purchase tobacco products regardless of age.[citation needed] Germany raised the purchase age from 16 to 18 on September 1, 2007. In the unadjusted analyses (Table 3), those planning for vocational education or extra year/discontinuation had higher S-EC compared with those planning for GUSS. Among girls, those without educational aspirations also had higher S-EC.

In smoking and school disengagement (e.g. truancy), students often choose to affiliate with similar peers [28, 29]. Smoking prevalence has been lower in schools where educational attainment and attendance are better than predicted based on student socio-demographic factors, indicating the importance of positive school ethos [30]. Yet, other school-level factors than school connectedness [22] have rarely been studied in connection with susceptibility. Youth use of e-cigarettes has surpassed youth use of regular combustible cigarettes in Delaware. Approximately 38 percent of Delaware high school students reported ever trying an electronic vapor product. Finally, the researchers compared the levels of nicotine in the blood serum of people after they had vaped e-cigarettes with the levels in people who smoked traditional cigarettes.

The Centers for Disease Control and Prevention (CDC) report that vaping nicotine can permanently affect brain development in people under the age of 25. The researchers concluded that vaping with and without nicotine disrupts typical lung function in otherwise healthy people. The researchers reported a number of adverse effects on both types of cells, including toxicity, oxidation, and inflammation. However, these results aren’t necessarily generalizable to vaping in real life. A 2019 study assessed data from a nationwide survey of nearly 450,000 participants and found no significant association between e-cigarette use and heart disease. The authors also described moderate evidence suggesting that taking a puff from an e-cigarette increases blood pressure.

The length of time spent vaping can be much longer than smoking a standard cigarette. While most cigarettes are smoked within two to five minutes, e-cigarettes can last up to 20 minutes, delivering more nicotine and damaging chemicals to the lungs. In addition, some vaping mixtures can contain 20 times the nicotine that a single cigarette contains. This study builds on the findings of an earlier randomized clinical trial of This is Quitting conducted among roughly 2,600 young adults ages 18 to 24.

E-cigarettes have been allowed to stay on the market for years without undergoing a full review of their public health impact, sparking a sustained and ongoing crisis of youth use. As of November 2023, the FDA has not completed reviewing all applications from e-cigarette makers to market their products, leaving many e-cigarettes on the market while waiting for a decision. To date, the FDA has denied permission to market flavored and menthol e-cigarette products such as Vuse Solo, Vuse Vibe, Vuse Ciro, and Vuse Alto. The FDA has denied permission to market many non-tobacco and non-menthol flavored e-cigarette products, however, many of those denials are currently under judicial or supervisory review. In recent years, the FDA has increased enforcement efforts around e-cigarette manufacturers and retailers for continuing to sell youth-appealing e-cigarettes. These actions include issuing warning letters, fines, injunctions, and joint operations with other federal officials to seize imports of unauthorized e-cigarette products.

This was especially the case for people aged 14 to 17 (74%) and 18 to 24 (68%). The 2022–‍2023 NDSHS was conducted before these restrictions were put into place. At the time, in most jurisdictions, it was legal for adults to purchase e‑cigarettes that did not contain nicotine from a broad range of retail settings, including those used to purchase tobacco products. Prior to 2024, adults could also import nicotine e‑cigarettes with a prescription via the personal importation scheme. The first study found that vaping can worsen several heart disease risk factors at levels equal to tobacco cigarettes, while the second found that e-cigarettes decrease blood flow in the heart even more than tobacco cigarettes. However, e-cigarettes still pose health risks, even without nicotine.

Adjusted analyses revealed that the type of e-cigarette device used played no role in the rates of cigarette discontinuation. Data were taken from the nationally representative Population Assessment of Tobacco and Health Study (PATH), which assessed participants through audio-based, computer-assisted self-interviews in English or Spanish. Interviews were conducted in "waves" -- October 2014 to October 2015, October 2015 to October 2016, December 2016 to January 2018, and December 2018 to November 2019.

E-cigarettes aren't thought of as 100% safe, but most experts think they're less dangerous than cigarettes, says Neal Benowitz, MD, a nicotine researcher at the University of California at San Francisco. Cigarette smoking kills almost half a million people a year in the United States. Most of the harm comes from the thousands of chemicals that are burned and inhaled in the smoke, he explains. E-cigarettes are battery-operated devices that can look like a real cigarette or pen.

"Popcorn lung" is another name for bronchiolitis obliterans (BO), a rare condition that results from damage of the lungs’ small airways. BO was originally discovered when popcorn factory workers started getting sick. The culprit was diacetyl, a food additive used to simulate butter flavor in microwave popcorn.

Nicotine yields for different e-cigarette brands have been reported from 2 to 313 µg puff−1 while for conventional cigarettes smoke the values ranged from 170 to 232 µg puff−16,31,36,48,64. Nicotine poisoning refers to the toxic effects of consuming nicotine, a chemical in all tobacco products. A recent increase in poisonings is due to liquid nicotine, a product in the popular e-cigarette. Symptoms include vomiting, rapid heart rate, unsteadiness and increased salivation. The comprehensive review of the evidence finds that almost all of the 2.6 million adults using e-cigarettes in Great Britain are current or ex-smokers, most of whom are using the devices to help them quit smoking or to prevent them going back to cigarettes. It also provides reassurance that very few adults and young people who have never smoked are becoming regular e-cigarette users (less than 1% in each group).

Nicotine use can have an impact on learning, memory and attention and increase the likelihood of addiction to other drugs in the future. While some people have reported that using e-cigarettes has helped them quit smoking, there are other proven, safe and effective options that should be explored first. It's important to help protect children and teens from using or being exposed to the harmful vapor from e-cigarettes. Talk with your pediatrician for more information about these products and keeping your child safe and healthy. Your regional Pediatric Environmental Health Specialty Unit (PEHSU) also have staff who can also talk with you about environmental toxins.

U.S. Surgeon General Vivek Murthy, MD, MBA, also highlighted that vaping "could be a major form of harm reduction for adults," although "not zero risk," but expressed strong concern over youth vaping. With the increasing use of e‑cigarettes, there has been greater support for policies aimed at controlling the prevalence of e‑cigarettes. You may also want to make an appointment with a doctor if you think vaping is behind any new symptoms, such as coughing, difficulty breathing, or increased heart rate.

Upon the selection of the educational track, students may already have normative perceptions of smoking in vocational schools, such as understanding of smoking as an integral and expected practice in these schools and professions [8]. These perceptions may increase S-SM and other nicotine product use, also among students with better academic performance. Student network characteristics and their associations with smoking vary between schools [28].

That’s about twice as many people as those who used other methods to quit smoking. Of people who used other methods, 91% kicked nicotine products altogether. People usually think vaping isn’t as bad as cigarette smoking, but the mist you breathe in still has nicotine and other harmful chemicals in it. Vaping isn’t safe and can cause health problems, including life-threatening lung injuries.

The inhaled vapor may contain nicotine (the addictive drug in tobacco), flavorings, and toxins—including ones that cause cancer. People who have already switched completely from smoking to e-cigarettes should not switch back to smoking (either solely or along with e-cigarettes), which could expose them to potentially devastating health effects. It's important to know the US Centers for Disease Control and Prevention (CDC) has stated that sometimes e-cigarette products are changed or modified and can have possibly harmful or illegal substances from unknown sources. Get regular updates on the health effects of tobacco, public health educational resources, and highlights on current tobacco issues and regulations.

And, our starter kits and disposable vape pens are a great, simple way to make the switch from smoking to vaping. We also have a wide selection of advanced kits for vapers who prefer high-powered cloud chasing e-cigs. Increasing consumer awareness of the environmental toxicity and dangers posed by discarding e-cigarette waste into landfills and encouraging vapers to quit are the best ways to protect the environment from tobacco product waste. Currently, there is no standardized way to recycle e-cigarettes in the U.S. Starting in 2019, the Drug Enforcement Agency (DEA) began accepting e-cigarette devices and cartridges during their annual National Prescription Take Back Day, although the DEA cannot accept devices containing lithium ion batteries.

Despite that, e-cigarettes are more popular among U.S. teens than any other form of tobacco. Electronic cigarettes are battery powered devices that people use to heat liquid into a vapor that can be inhaled. Some studies have shown that vaping by some youth may be linked to later use of regular cigarettes and other tobacco products. Using e-cigarettes may play a part in some kids or teens wanting to use other, more harmful tobacco products. Although the term "vapor" may sound harmless, the aerosol that comes out of an e-cigarette is not water vapor and can be harmful. The aerosol from an e-cigarette can contain nicotine and other substances that are addictive and can cause lung disease, heart disease, and cancer.

There's always a chance that the fail-safe could fail, though, which is why we don't consider these as safe as other vaping devices. The biggest risks in vaping devices come when you get into highly customizable "mods." These devices allow for lots of fine-tuning in terms of the internal electrical setup. But this added flexibility means more possibilities for health hazards. You'll have to be careful not to buy knock-off vape liquids with unhealthy contaminants, for one thing.

The researchers — from Truth Initiative and Brown University — found that after seven months had gone by, about 38% of participants in the This is Quitting program reported not vaping in the previous 30 days, compared with 28% in the assessment-only group. E-cigarettes are the most commonly used tobacco product among adolescents. (CNN) — For teens who want to stop vaping nicotine, an interactive text message program was found to be effective at helping them quit.

Tetrahydrocannabinol (THC)-containing e-cigarette or vaping products was linked to most EVALI cases. Emergency department visits related to e-cigarette, or vaping, products have sharply declined in recent years, but the CDC continues to monitor reports. In 2022, e-cigarettes remained the most common tobacco product used by high school (16.5%) and middle school (4.5%) students in the last 30 days. And more than a quarter (27.6%) of current youth e-cigarette users say they use an e-cigarette product every day.

However, there is no requirement that the Electronic Cigarette tax needs to be broken out separately from the sales tax on an invoice or receipt, but both taxes must be collected on the transaction for products subject to the tax. To report transactions and taxes due for the preceding month, Form ECG-103 must be filed the 15th day of each month using INTIME. The sale by a merchant of closed system cartridges, vapor products, open system containers and consumable material are retail transactions that are subject to Sales tax. Therefore, a retailer must register as a retail merchant with DOR and collect and remit Sales tax on these items and all other tangible personal property sold by the store. Youth vaping has declined from all-time highs in recent years, but 2.8 million middle and high school students still use it, according to federal survey data. Vaping can damage your lungs and put you at higher risk of respiratory infections, including COVID-19.

We are aware of this issue and are diligently working on restoration. Check with your airline on any limitations on the number of devices that can be carried for personal use by a passenger. WHO strives to build a safer, healthier world for everyone, everywhere.

Various studies suggest the vapors from e-cigarettes contain several cancer-causing substances, as well as incredibly tiny particles of tin, chromium, nickel and other heavy metals, which, in large enough concentrations, can damage the lungs. These particles likely fleck off the solder joints or metal coil in the devices when heated. Because they are so small, the tiniest bits of metal, known as nanoparticles, can travel deep into the lungs. There they could exacerbate asthma, bronchitis—an inflammation of the tubes that carry air to and from the lungs—and emphysema—a disease in which the lungs' many air sacs are destroyed, leaving patients short of breath. So far there are not enough data to say with certainty whether e-cigs worsen these disorders. E-cigarettes have a battery-operated component that heats liquid containing nicotine, flavorings, and other chemicals.

Even liquid nicotine spilled on the skin can be poisonous within minutes. A standard vape kit is usually an electronic cigarette - this usually consists of a battery and tank that allows you to fill it with e-liquid. But you can get many types of vapes, such as pod mods, sub-ohm kits, cigalikes, and many more. We have a wide range of vape kits available, whether you’re looking for a refillable pod vape, a heated tobacco product or a prefilled pod kit.

Juul’s C.E.O., Kevin Burns, who is fifty-four, has a friendly dad-who-loves-his-vacation-house demeanor. Burns described Juul to me as a "cigarette-killing company." Before he accepted the job, he said, he convened an informal focus group in his kitchen with his son, who’s in high school, and a few of his son’s friends. He asked them why they had these things, when they got them, how prevalent they were. "We have frustrations about how the product is glorified on social media," he told me. I admitted to Winickoff that I was probably endangering my lungs as a weed smoker. He gamely pointed out that I could look into ingested forms of marijuana, and noted that my brain was in a much more stable place than it had been when I was twenty-one.

Other important components in the aerosols include silicate particles from the fiberglass wicks or silicone [89,90,91]. Many of these products are known to cause abnormalities in respiratory function and respiratory diseases [89,90,91], but more in-depth studies are required. Interestingly, the battery output voltage also seems to have an impact on the cytotoxicity of the aerosol vapours, with e-liquids from a higher battery output voltage showing more toxicity to A549 cells [30]. The lethal dose of nicotine for an adult is estimated at 30–60 mg [52].

The harmful effects of CS and their deleterious consequences are both well recognised and widely investigated. However, and based on the studies carried out so far, it seems that e-cigarette consumption is less toxic than tobacco smoking. This does not necessarily mean, however, that e-cigarettes are free from hazardous effects. Indeed, studies investigating their long-term effects on human health are urgently required. In this regard, the main additional studies needed in this field are summarized in Table 3.

According to the study, 40.1% of 1,018 adolescents between the ages of 14 and 29 surveyed said they refilled devices not intended to be refilled and 35.8% recharged the battery of vaping pods meant to be thrown out after one use. Others reported mixing nicotine and cannabis liquids in devices designed only for nicotine. The decision lends new credibility to vaping companies’ longstanding claim that their products can help blunt the toll of smoking, which is blamed for 480,000 U.S. deaths annually due to cancer, lung disease and heart disease. Some of the harmful substances emitted in secondhand e-cigarette aerosols are similar to those in secondhand tobacco smoke.

This can be the result of an injury — such as a gunshot or knife wound — or when air blisters on the top of the lungs rupture and create tiny tears. Single-use, disposable e-cigarettes cost anywhere from $1 to $15 each or more. Rechargeable starter kits with multiple pods can cost anywhere from $25 to $150 or more. They may also have added flavors and contain a variety of other chemicals. 15 State of California Environmental Protection Agency Office of Environmental Health Hazard Assessment Safe Drinking Water and Toxic Enforcement Act of 1986. (2013).Chemicals known to the State of California to cause cancer or reproductive toxicity.

New 'pod-mod' style vape products are similar in shape and size to JUUL® and other vape sticks but are disposable. New York State has enacted strong policies to protect youth from accessing tobacco products and denormalize tobacco and nicotine use to prevent lifelong addiction, illness, and early death. Policies include banning the sale of flavored vapor products, ending price discounts on tobacco and vapor products, and banning the exterior display of tobacco and vapor product ads near schools. E-cigarettes also are controversial because of various regulatory issues. In January 2010, following a lawsuit by an e-cigarette distributor, the U.S.

Instead of bathing lung tissue with a therapeutic mist, just as a nebulizer does, vaping coats lungs with potentially harmful chemicals. E-liquid concoctions usually include some mix of flavorings, aromatic additives and nicotine or THC (the chemical in marijuana that causes psychological effects), dissolved in an oily liquid base. "We think that some of the vaporized elements of the oil are getting deep down into the lungs and causing an inflammatory response," explains Broderick.

Each time you resist a tobacco craving, you're one step closer to stopping tobacco use for good. PHE’s remit letter for 2014 to 2015 requested an update of the evidence around e-cigarettes. PHE commissioned Professors Ann McNeill and Peter Hajek to review the available evidence. The review builds on previous evidence summaries published by PHE in 2014. All of our local NHS Stop Smoking Services now proactively welcome anyone who wants to use these devices as part of their quit attempt and increase their chance of success. Cancer Research UK is funding more research to deal with the unanswered questions around these products including the longer-term impact.

Almost 9 in 10 people (86%) supported prohibiting the sale of e‑cigarettes to people under 18 years of age, a substantial increase from 2019 (79%). Social and economic factors shape people’s behaviours of vaping or smoking. Generally, people living in the most disadvantaged socioeconomic areas were the most likely to currently smoke regular cigarettes but not use e‑cigarettes (13.2%). In contrast, people living in the most advantaged socioeconomic areas were the most likely to use e‑cigarettes but not smoke regular cigarettes (6.6%) (Figure 4). Young people aged 18 to 24 were the most likely to have used e‑cigarettes in 2022–‍2023, with almost 1 in 2 (49%) having used them at least once in their lifetime, and over 1 in 5 (21%) currently using e‑cigarettes in 2022–‍2023. More information on young people’s use of vapes and e-cigarettes can be found online.

In general, e-cigarettes are not safe for young people or people who are pregnant. Vaping is no safer for developing fetuses than smoking traditional cigarettes. They may also resemble sleek electronic devices, making them appealing to younger users.

The program’s curriculum includes a four-part series of lessons, with one set for fifth through eighth graders and another for high schoolers. The lessons teach students about the dangers of vaping, vaping marketing and resources for quitting vaping. Students that go through the program are 45% less likely to vape, according to Bianco. This is Quitting was developed by Truth Initiative, a nonprofit focused on ending tobacco use, as a free and anonymous text messaging program to help young people quit vaping.

Nicotine pouches, led by top-selling Zyn by Swedish Match, have become increasingly popular among adult tobacco consumers, particularly those trying to lower or end their traditional or electronic cigarette consumption. Chalmers said some students are realizing the dangers of vaping after seeing their peers struggle with nicotine addictions. She believes that adding the CATCH My Breath education only solidifies it for them.

Vape flavors like mint and mango appeal to young people and mask the harshness of nicotine. The small, discreet size of vapes and e-cigarettes make them easy to conceal at school and home. The bottom line is e-cigarettes and vapes are unsafe for kids, teens and young adults. Nicotine is harmful to the developing brain and the use of e-cigarettes as a teen increases the likelihood of smoking cigarettes as an adult. The chemical additives and flavoring can also cause unwanted health effects.

Electronic smoking devices (or ESDs), which are often called e-cigarettes, heat and vaporize a solution that typically contains nicotine. The devices are metal or plastic tubes that contain a cartridge filled with a liquid that is vaporized by a battery-powered heating element. The aerosol is inhaled by the user when they draw on the device, as they would a regular tobacco cigarette, and the user exhales the aerosol into the environment. Electronic cigarettes (E-Cigarettes) are battery-powered devices that function by heating a liquid into an aerosol that is inhaled by the user.

Founded in 1913 as the Harvard-MIT School of Health Officers, the School is recognized as America’s oldest professional training program in public health. This study explored the prevalence of S-SM, S-EC, and S-SN among adolescents in a country with advanced tobacco control regulations. We found that the susceptibility was highest for e-cigarette use, followed by smoking and snus use. S-SM was more common among girls, whereas S-EC and S-SN were more common among boys. In our analysis, levels of carbonyls were considerably reduced relative both to other studies of e-cigarettes and to Ky1R6F cigarette smoke.

In the vaping liquids that contain nicotine, the level of nicotine can vary widely. Prior to July 2021 in Canada, vaping substance nicotine strengths ranged from 0 to over 60 mg/ml of nicotine. Since July 2021, the Nicotine Concentration in Vaping Products Regulations establish a maximum concentration of 20 mg/mL for vaping products manufactured in or imported into Canada. Market size is clearly affected by national laws governing the sale of e-cigarette products. In 2016, the Washington State Legislature passed a law (RCW 70.345) to regulate vapor products.

Restrictions on importation, packaging and flavourings will come into effect in early 2024 (TGA 2023). Between 2012 and 2022, most Australian jurisdictions have amended their laws to further restrict the advertising and sale of e‑cigarettes (Department of Health and Aged Care 2023b). Recent reports have linked serious lung injury – and even deaths – to vaping. According to the CDC, cigarette smoking causes nearly 1 out of every five deaths in the United States. It’s possible that we don’t yet know all the physical effects of vaping. Numerous studies have been performed to evaluate the safety/toxicity of e-cigarette use both in vivo and in in vitro cell culture.

If you're not interested in giving up nicotine but you want to leave smoking behind, an Elf Bar disposable vape might be your best choice. We make a living building vape pens that are free from potentially harmful substances. Our disposable vapes are designed to give you the closest thing possible to a pure dose of caffeine or melatonin, without the harmful ingredients sometimes found in vape juice. This list of the 9 safest vapes will help you avoid those toxic components and puff away without fear. There is no good evidence that second-hand vapour from e-cigarettes is harmful.

Teens and young adults can join for free by texting DITCHVAPE to 88709. See " Local restrictions on flavored tobacco and e-cigarette products " for a full report on local flavored tobacco policies. For those who prefer a more "natural" vape experience, Kind Juice provides a range of liquids derived entirely from organically grown plants. The flavors are extracted using relatively gentle solvents, while the vegetable glycerine carrier fluid is made from plant oils using hydrolysis. Kind Juice products contain no additives, nicotine, or psychoactive ingredients, though some have CBD. Many people stick to regulated mods, which include circuit boards that can help prevent problems like power surges.

And Puerto Rico have passed comprehensive smoke-free indoor air laws that include e-cigarettes, as of March 31, 2023. These laws prohibit smoking and the use of e-cigarettes in indoor areas of private worksites, restaurants, and bars. In our fight to end youth and young adult nicotine addiction, we focus on the issues that matter most.

Still, many people, including teens and young adults drawn to vaping, may not realize that, Bittoni said. Other popular brands, like Puff Bar, have received warnings from regulators about the sale of flavored devices as well. Following the Golden State, Washington had the second-lowest amount of youth vapers, at eight percent. In the Evergreen state, the legal age to purchase vapes is 21, and there is a ban on all flavored varieties. Last year, Alaska Senate President Gary Stevens, a Republican, introduced Senate Bill 89, aimed at imposing the state's first-ever tax on e-cigarette products. Wyoming had the highest rate of youth vapers, with 30 percent of kids under 18 reporting they had used e-cigarettes in 2023.

The last reviewed date indicates when the evidence for this resource last underwent a comprehensive review. Reviewed by Kenneth Uy, a health coach and tobacco treatment specialist at Henry Ford Health. Patrick O’Connor, MD, Yale Medicine’s chief of general internal medicine, who has dedicated his career to researching opioid and alcohol drug abuse, points to similarities between epidemic cigarette use in the 1940s and 50s, and e-cigarette use now.

One of the first studies in humans involved the analysis of 9 volunteers that consumed e-cigarettes, with or without nicotine, in a ventilated room for 2 h [8]. Pollutants in indoor air, exhaled nitric oxide (NO) and urinary metabolite profiles were analysed. The results of this acute experiment revealed that e-cigarettes are not emission-free, and ultrafine particles formed from propylene glycol (PG) could be detected in the lungs. In line with these observations, dysregulation of lung homeostasis has been documented in non-smokers subjected to acute inhalation of e-cigarette aerosols [10]. Globally, there is an ongoing debate about whether e-cigarettes are a threat or an opportunity to public health.

Many people diagnosed with EVALI need to be treated in a hospital where medications can be closely monitored, and respiratory support is readily available. "I screen all of my patients, any child over age 12, since [vaping] can exacerbate underlying conditions like asthma," says Yale Medicine pediatric pulmonologist Pnina Weiss, MD. To learn more about e-cigarettes, here are resources from the American Cancer Society and the FDA. There are some e-cigarette brands that claim to be nicotine-free but have been found to contain nicotine. For medical questions, we encourage you to review our information with your doctor.

With regards to toxicity, little is known about the effects of humectants when they are heated and chronically inhaled. Indeed, the latter study established that one e-cigarette puff results in a PG exposure of 430–603 mg/m3, which is higher than the levels reported to cause airway irritation (average 309 mg/m3) based on a human study [55]. The same study established that one e-cigarette puff results in a glycerol exposure of 348–495 mg/m3 [57], which is close to the levels reported to cause airway irritation in rats (662 mg/m3) [58]. Results from in vitro studies are in general agreement with the limited number of in vivo studies.

The FDA lists 93 harmful or potentially harmful chemicals found in regular cigarettes, and the National Cancer Institute (NCI) describes cigarettes as having more than 7,000 chemicals in them. Because e-cigarettes contain fewer chemicals the industry has presented them as a healthier alternative to regular cigarettes. But vape liquids can still contain nicotine, a highly addictive drug.

For example, in an analysis using primary human umbilical vein endothelial cells (HUVEC) exposed to 11 commercially-available vapours, 5 were found to be acutely cytotoxic, and only 3 of those contained nicotine [24]. In addition, 5 of the 11 vapours tested (including 4 that were cytotoxic) reduced HUVEC proliferation and one of them increased the production of intracellular reactive oxygen species (ROS) [24]. Three of the most cytotoxic vapours—with effects similar to those of conventional high-nicotine CS extracts—also caused comparable morphological changes [24]. Endothelial cell migration is an important mechanism of vascular repair than can be disrupted in smokers due to endothelial dysfunction [25, 26]. E-cigarettes are sometimes called e-cigs, vapes, vape pens, e-hookahs, and electronic nicotine delivery systems or ENDS.

Of the participants who were not using e-cigarettes, only 5.8% had quit smoking altogether by the end of the survey, while 9.9% had stopped smoking daily. At the end of the survey, 28% of smokers using e-cigarettes daily had ceased smoking tobacco altogether, while 45.5% had ceased smoking tobacco daily. The AHA notes that while vaping liquids contain fewer contaminants than cigarettes, they are not entirely safe. Based on the available evidence, smoking appears more harmful than vaping, but this does not mean that vaping is safe.

Heating the liquid (e-juices) causes formation of an aerosol which users inhale into their lungs. These electronic smoking devices come in different shapes and sizes and can look like regular cigarettes, pens, and even flash drives (similar to the popular brand "JUUL"). E-cigarettes go by many names including vapes, e-cigs, e-pens, e-hookahs and mods. The Food and Drug Administration (FDA) extended its regulatory authority over tobacco products to include e-cigarettes in May 2016.

Dr. Amanda Graham, chief of innovations at Truth Initiative, said youth e-cigarette use remains a serious public health concern. Launched in January 2019, the This is Quitting program has amassed more than 750,000 enrolled to date and is designed for teens and young adults looking to quit e-cigarettes. Although advertising may make it look convenient and appealing, it’s important to know that these products deliver varying amounts of the addictive chemical nicotine, which can negatively impact your learning, attention span and proneness to addiction. Many teens are taking things a step further, adding cannabis, CBD oils and other dangerous additives to vaping devices. When patients show up to the emergency department in respiratory distress from vaping, it can be challenging for physicians to treat them due to the difficulty in correctly identifying what they inhaled, especially when they are intubated or unconscious. Truth Initiative, the organization behind truth®, the nationally recognized, proven-effective youth tobacco and opioid prevention public education...

More research needs to be done to understand the long-term health effects of secondhand exposure to e-cigarette vapor. Secondhand exposure to e-cigarette vapor is said to be less toxic than secondhand exposure to cigarette smoke. However, secondhand vapor is still a form of air pollution that probably poses health risks. N.L.B. serves as a consultant to pharmaceutical companies that market or are developing smoking cessation medications, and has provided expert testimony in litigation against tobacco companies. N.A.R. consults with and has received a research grant from Achieve Life Sciences for development of a smoking cessation medication, and receives royalties from UpToDate (an online medical textbook) as author of sections on e-cigarettes.

This includes banning the sale of all non-prescription e-cigarettes and prohibiting the sale of any disposable or single-use e-cigarettes. Health experts are concerned about the various chemical ingredients within e-cigarettes. Even though it is illegal to sell e-cigarettes and e-liquids containing nicotine in Victoria, there is no guarantee that products purchased will not contain nicotine. Research now shows that young people who initially use e-cigarettes, who have never smoked before, are 3 times more likely to take up tobacco smoking. That aerosol is often called ‘vapour’ and inhaling it from an e-cigarette is known as ‘vaping’.

In fact, the overall evidence points to e-cigarettes actually helping people to give up smoking tobacco. There is no evidence that e-cigarettes are undermining England’s falling smoking rates. Instead the evidence consistently finds that e-cigarettes are another tool for stopping smoking and in my view smokers should try vaping and vapers should stop smoking entirely. E-cigarettes not only pose substantial health risks to youth and young adults, they pose a significant environmental threat (see the Truth Initiative fact sheet on Tobacco and the Environment). Almost half (49.1%) of young people don’t know what to do with used e-cigarette pods and disposable devices. A second brand of e-cigarettes—marketed as Nixotine, Nixodine, Nixamide and Nic-Safe—contained a nicotine analog called nicotinamide, also at levels lower than the labels indicated, and combined with undisclosed amounts of 6-methyl nicotine.

We would argue that further studies with chronic administration of low doses of nicotine are required to clearly evaluate its impact on carcinogenicity. In this line, a study compared the acute impact of CS vs. e-cigarette vaping with equivalent nicotine content in healthy smokers and non-smokers. Both increased markers of oxidative stress and decreased NO bioavailability, flow-mediated dilation, and vitamin E levels showing no significant differences between tobacco and e-cigarette exposure (reviewed in [20]). Inasmuch, short-term e-cigarette use in healthy smokers resulted in marked impairment of endothelial function and an increase in arterial stiffness (reviewed in [20]). Similar effects on endothelial dysfunction and arterial stiffness were found in animals when they were exposed to e-cigarette vapor either for several days or chronically (reviewed in [20]).

The ACS encourages young people currently using any of these products to ask for help in quitting and to quit as soon as possible. E-cigarettes can be especially harmful for young people because nicotine affects them in different ways than adults. People who use e-cigarettes should make sure they do not vape around children and ensure they always store e-cigarettes and e-liquids out of reach of children when not in use.

"This is Our Watch" is a voluntary education program with resources to help tobacco retailers better understand and comply with FDA tobacco regulations. Tobacco retailers play a direct role in protecting kids from nicotine addiction and the deadly effects of tobacco use. Learn what tobacco retailers need to do to comply with the rules designed to prevent our nation's youth from becoming the next generation of Americans to die prematurely from tobacco-related disease.

A 2018 study assessed the lung function of 10 people who had never smoked cigarettes immediately after vaping fluids, either with or without nicotine. However, the researchers concluded that, overall, vaping is thought to be less harmful to the heart than smoking cigarettes. However, they found that people who smoked conventional cigarettes and e-cigarettes were more likely to have heart disease. In a recently published randomised trial of 886 subjects who were willing to quit smoking [100], the abstinence rate was found to be twice as high in the e-cigarette group than in the nicotine-replacement group (18.0% vs. 9.9%) after 1 year.

A recent study compared the acute effects of e-cigarette vapor (with PG/vegetable glycerine plus tobacco flavouring but without nicotine) generated from stainless‐steel atomizer (SS) heating element or from a nickel‐chromium alloy (NC) [92]. Neither the air‐exposed rats nor those exposed to e-cigarette vapor using SS heating elements developed respiratory distress. In contrast, 80% of the rats exposed to e-cigarette vapor using NC heating units developed clinical acute respiratory distress when a 70‐W power setting was employed. Thus, suggesting that operating units at higher than recommended settings can cause adverse effects. Nevertheless, there is no doubt that the deleterious effects of battery output voltage are not comparable to those exerted by CS extracts [30] (Figs. 1 and 2). "Our findings are consistent with earlier evidence that sufficient nicotine replacement can be helpful for quitting smoking.

When studying tobacco cigarettes, researchers rely on smoking machines that simulate how frequently a typical smoker takes a puff and how much smoke is inhaled with each breath. No one has yet determined how much e-cig vapor the typical user breathes in, so different studies assume different amounts of vapor as their standard, making it difficult to compare their results. Tracing what happens to that vapor once it is inhaled is equally problematic.

E-cigarettes, also known as e-cigs, vapes, vape pens, and electronic nicotine delivery systems (ENDS), are experiencing rapid growth in popularity, especially among teens and young adults. They come in a variety of forms, sometimes looking like USB flash drives, pens, and other items that make them hard for parents and teachers to spot. Other electronic devices that heat tobacco instead of liquid nicotine, such as IQOS, are not considered e-cigarettes. Teens cannot participate in such studies, but "we all agree that e-cigs are not a good thing for youth and nonsmokers," Dr. Baldassarri says. The Food and Drug Administration on Friday authorized the first menthol-flavored electronic cigarettes for adult smokers, acknowledging that vaping flavors can reduce the harms of traditional tobacco smoking.

Federal, state, and/or local governments need to set clear standards on environmentally responsible e-cigarette waste disposal and hold the industry accountable for adhering to them. E-cigarette manufacturers introduced a new tobacco product that soared in popularity with little thought on how to responsibly dispose of the resulting tons of e-cigarette waste. The group then performed a statistical analysis to determine group differences in vascular function before and after vaping.

We also left out propylene glycol, a petroleum byproduct often used as a flavor enhancer. This stuff isn't considered toxic, but it adds a harsh edge to your inhale, and we wanted to stick to strictly plant-based components. I understand that for a few moments during your meal you may have a sniff of my vape that you don’t care for, but I’m sure that it isn’t as horrible as you make it sound in your rant. Life is full of mild unpleasantries that we all must deal with on a daily basis, but we can choose to deal with them or let them torment us.

Despite being marketed as a safer alternative to traditional cigarettes, e-cigarettes contain numerous harmful substances such as formaldehyde, heavy metals, and carcinogens, he added. Part of the difficulty in curbing youth e-cigarette use has been the intensity of the industry’s marketing towards kids, particularly through social media influencers, said Bianco. In the 2021 Youth National Tobacco Survey, 73.5% of youth that use social media reported seeing e-cigarette–related content.

Our experts provide care to both kids and adults with complex lung issues from all over Southern California and beyond. Teens today have access to more potentially misleading information than at any other time in history. They’re also bombarded by more sources of advertising than ever before.

This ban excludes disposable e-cigarette devices, which are sold in many appealing flavors and are relatively inexpensive. And are now the most popular type of e-cigarette used by adolescents. Nicotine is highly addictive and may lead to nicotine cravings and development of tolerance (the need to use more often in order to have the same effect). Nicotine addiction can negatively affect relationships and impair performance at school, at work, or in other activities. Researchers have also identified vitamin E acetate, a chemical added to some THC-containing vaping products, as the main—but possibly not the only—cause of the illness.

JUULs very closely resemble a USB drive, can be charged in a USB port, and emit little to no detectable vapor or odor. Due to their easily concealable design, they are of particular concern with regard to youth use. DOH urges all people to be very careful when it comes to your health. Even if a substance has not yet been proven to be dangerous, there is no guarantee it is safe. You don’t actually light up an e-cig; they’re powered by a rechargeable lithium battery. Instead of burning tobacco, the "e-liquid" is vaporized in a heating chamber when the user inhales.

This includes quit coaching, up to 2 weeks of nicotine replacement therapy, and a youth digital program for those ages 13-17. Vuse, owned by Reynolds American, and Juul control about 60% of the market, while hundreds of disposable brands account for the rest. While nicotine is the addictive substance in cigarettes, most of the harm from smoking comes from the thousands of other chemicals in tobacco smoke, many of which are toxic.

Vape aerosols may also increase the risk of heart disease, lung cancer, and asthma complications. The substitution was especially evident among cigarette brands popular with young people aged 20 and under, suggesting that flavor restrictions may increase smoking among youth as well as adults. The immense popularity of electronic cigarettes, or e-cigarettes, among young people has led many policymakers to restrict the sale of flavored varieties. Proponents of e-cigarettes claim they’re safer than smoking because they don’t contain the more than 60 cancer-causing chemicals in tobacco smoke and are not combustible. But e-cigs still deliver harmful chemicals, including nicotine, the extremely addictive substance in cigarettes.

We want to make a difference in the lives of our users, and create products that can fit all levels and styles of vapers, to help as many as possible. Stanford Medicine Tobacco Prevention ToolkitTheory-based and evidence-informed resources created by educators, parents, and researchers aimed at preventing middle and high school students' use of tobacco and nicotine. There are several resources available to assist with learning more about e-cigarettes and educating youth about the risks. Resources are available for parents, educators, and health care providers. According to the 2017 Behavior Risk Factor Survey (BRFS) conducted by DHSS, 4.8 percent of Delaware adults currently use e-cigarettes, roughly the same percentage reported in the 2016 survey.

In December 2019, the federal government raised the legal minimum age of sale of tobacco products from 18 to 21 years, and in January 2020, the FDA issued a policy on the sale of flavored vaping cartridges. The e-liquid in most e-cigarettes contains nicotine, the same addictive drug that is in regular cigarettes, cigars, hookah, and other tobacco products. However, nicotine levels are not the same in all types of e-cigarettes, and sometimes product labels do not list the true nicotine content. Products marketed for therapeutic purposes (for example, marketed as a product to help people quit smoking) are regulated by FDA’s Center for Drug Evaluation and Research (CDER).

What may be the most important message of all is that e-cigarettes and vaping come with many health unknowns, Dr. O’Connor adds. "You see plumes of what looks like steam coming out of people’s mouths on the street when they are vaping, and I think they assume it’s mostly safe, mostly water. But these liquids used in vaping are filled with all kinds of stuff [like nicotine, marijuana, flavoring agents, chemicals], and we don’t always know what else is in there," he says. When potentially risky behaviors experience an uptick in popularity, health researchers are never far behind—gathering data.

Conducted from October 2021 to October 2023, the study involved 1,503 adolescents ages from across the United States who reported past 30-day e-cigarette use and were interested in quitting. Compared to a control group, participants who received the interactive text message program were 35% more likely to report not using nicotine at the 7-month study endpoint. Quit rates were 37.8% in the intervention groups compared to 28% in the control group. In North Macedonia, Italy, Malta, Austria, Luxembourg, and Belgium, the age for legal vending is 16. Since January 1, 2007, all cigarette machines in public places in Germany must attempt to verify a customer's age by requiring the insertion of a debit card.

Given their relatively recent introduction, there has been little time for a scientific body of evidence to develop on the health effects of e-cigarettes. Notably, the reverse was not true—students who said they smoked cigarettes were no more likely to report use of e-cigarettes when asked approximately 6 months later. Electronic cigarettes, or e-cigarettes, are tobacco products that have been sold in the U.S. for about a decade. They include e-pens, e-pipes, e-hookah, and e-cigars, known collectively as ENDS—electronic nicotine delivery systems. They're also sometimes called JUULs, "vapes" and "vape pens." E-cigarettes are the most commonly used tobacco products among kids—and it's become an epidemic. While much remains to be determined about the lasting health consequences of e-cigarettes, there’s evolving evidence about the health risks of e-cigarettes on the lungs—including irreversible lung damage and lung disease.

Next, we examined the e-cigarette emissions of flavouring compounds, together with acetic acid and propionic acid, as listed by the U.S. These compounds were not analysed in cigarette smoke because the Ky1R6F cigarette used in the study is an unflavoured US-blended cigarette and validated analytical methods for these compounds were not available. From the studied carbonyls, only acetaldehyde, acrolein and formaldehyde are included in the nine WHO TobReg priority smoke toxicants55. Relative to cigarette smoke, their percentage of reduction in the e-cigarette emissions was ≥ 98.8%. Liquid refills are sold in quantities of 10 mL to more than 30 mL (about two to six teaspoons) in a variety of nicotine strengths. The products come in flavors with attractive scents and inviting packaging.

This data brief demonstrates that teens whose environments put them at risk for use of e-cigarettes are more likely to try them. The study, published on May 23, 2022, in Tobacco Control, is the first to look at the health care costs of e-cigarette use among adults 18 and older. The second most supported measure, strengthening restrictions on the advertising and promotion of e‑cigarettes, was supported by 82% of people. In 2019, only 67% of people in Australia supported strengthening these restrictions. The proportion of people neither smoking regular cigarettes nor using e‑cigarettes has remained stable (Figure 3).

The FDA has the legal authority to regulate tobacco products containing nicotine from any source, including synthetic nicotine. In 2016, the FDA established a rule for e-cigarettes and their liquid solutions. Because e-cigarettes contain nicotine derived from tobacco, they are now subject to government regulation as tobacco products.

Guidance exists on best practices on this concept of accountability — known as end-producer responsibility — but isn’t enforced across the industry by any governing body. Substances from inhaled aerosol particles reaching the e-cigarette user’s lungs, blood, and brain. Minnesota’s middle school and high school students who have asthma who vaped or smoked in the past 30 days reported experiencing more frequent symptoms of asthma than students who did not have asthma who had not vaped or smoked.

In a major recent undertaking to help clarify the effects of e-cigarettes, the physician-investigator conducted a review of the best available evidence about vaping and lung harms. She and her co-authors published their roundup of the evidence in an article titled "Vaping and Lung Inflammation and Injury," which appeared online Feb. 10 in the journal Annual Review of Physiology. A study in the Journal of the American Medical Association in 2015 found a connection too. Researchers surveyed 2,500 Los Angeles high school students who had never smoked.

Long periods of dual use of cigarettes and e-cigarettes can result in harms to health similar to, or in addition to, the harms from exclusive use of cigarettes. Nicotine is the primary agent in regular cigarettes and e-cigarettes, and it is highly addictive. It causes you to crave a smoke and suffer withdrawal symptoms if you ignore the craving.

Probably the worst thing a parent could do for their child would be to buy an e-cigarette under the misconception that this might prevent them from smoking regular cigarettes, Krishnan-Sarin says. She encourages parents to talk openly and freely about vaping—with the caveat that they provide accurate information. "I think the problem is that parents lose credibility if they say something to try and convince their child, who then finds out that it isn’t true," she says. Vape pen and e-cigarette explosions from overheated, defective and/or modified device batteries have occurred, causing injury and serious health problems to users. Learn more about how to avoid vape battery explosions from the FDA or download the FDA's tips for avoiding battery explosions.

Parental smoking, positive attitude towards e-cigarette use in one’s age group, current smoking, and snus use increased S-EC, whereas liking school lowered it. At school level, both among girls and boys, a higher proportion of students liking school and being never-users lowered S-EC, whereas a higher proportion of students with positive attitudes towards e-cigarette use increased it. Among girls, a higher proportion of girls in the school, students with a high parental education and planning for GUSS lowered S-EC, but a higher proportion of students with parental smoking increased it.

They observed, on average, a 34 percent reduction in the femoral artery’s dilation. These findings suggest that vaping can cause significant changes to the inner lining of blood vessels, said study lead author Alessandra Caporale, PhD, a post-doctoral researcher in the Laboratory for Structural, Physiologic, and Functional Imaging at Penn. In this study, the researchers examined the impact of an e-cigarette that contained propylene glycol and glycerol with tobacco flavoring, but no nicotine, which study participants took 16, three-second puffs from. To evaluate vascular reactivity, researchers constricted the vessels of the study participants’ thigh with a cuff and then measured how quickly the blood flowed after its release. Using a multi-parametric MRI procedure, researchers scanned the femoral artery and vein in the leg before and after each vaping episode to see how vascular function changed.

A great example of this is the Riot Connex Pod Kit which uses magnets to attach replaceable cartridge-like flaovured pods to the batter. You can also get refillable pod mod kits, which use pods with built-in coils but require filling with your e-liquid. These can also appeal to beginners who like to experiment with different flavours but wish to keep the set-up as minimal as possible.

Even though you may not smell it, third-hand particulates cling to surfaces and dust and can be breathed deep into the lungs or absorbed through the skin.It’s easy to quit vaping.One vape pod delivers as much addictive nicotine as 20 cigarettes. Vaping trains the brain to expect more nicotine and creates the desire to vape even more. That makes it harder to stop vaping and also increases the chance that teens will go on to become smokers, too. E-cigarettes with nicotine are highly addictive and are harmful to health. Whilst long-term health effects are not fully understood, it has been established that they generate toxic substances, some of which are known to cause cancer and some that increase the risk of heart and lung disorders. Use of e-cigarettes can also affect brain development and lead to learning disorders for young people.

Most modern cigarettes are filtered, although this does not make the smoke inhaled from them contain fewer carcinogens and harmful chemicals. Nicotine, the psychoactive drug in tobacco, makes cigarettes highly addictive. About half of cigarette smokers die of tobacco-related disease and lose on average 14 years of life.

Experts have long suspected it, but a new study confirms that folks who vape and smoke tobacco face higher risks for lung cancer than if they'd done either alone. Propylene glycol, for example, is usually eaten (in cupcakes, soft drinks and salad dressings) or slathered onto the body (in soaps, shampoos and antiperspirants)—not breathed into the lungs. Many things that can be safely eaten—such as flour—can damage the lungs when inhaled. "We have little information about what happens to propylene glycol in the air," the federal Agency for Toxic Substances and Disease Registry says on its Web site.

Many grants on this topic are funded through the Tobacco Regulatory Science Program, an NIH partnership with FDA’s Center for Tobacco Products to fund research to inform FDA’s tobacco regulatory activities. Interestingly, most of these reports linking COVID-19 harmful effects with smoking or vaping, are based on their capability of increasing the expression of angiotensin-converting enzyme 2 (ACE2) in the lung. It is well known that ACE2 is the gate for SARS-CoV-2 entrance to the airways [106] and it is mainly expressed in type 2 alveolar epithelial cells and alveolar macrophages [107]. To date, most of the studies in this field indicate that current smokers have higher expression of ACE2 in the airways (reviewed by [108]) than healthy non-smokers [109, 110]. While tobacco products have been a long-standing public health issue, e-cigarette (aka e-cigs, vape pens, vapes) use has continued to gain popularity throughout the last decade. Poison centers began receiving calls about e-cigarettes and liquid nicotine products in 2010, which overlaps with the initial period where these products reached the U.S. market.
