While FDA has made progress in reviewing marketing applications for flavored e-cigarettes, it has repeatedly missed deadlines to complete its review of major products and failed to clear the market of these illegal flavored products. Here you will find the facts on vaping, based on scientific evidence and research, plus advice on how to use vapes (sometimes called e-cigarettes or e-cigs) as a tool to quit smoking. Battery-powered vape devices create an aerosol that looks like water vapor but contains nicotine, flavoring, and more than 30 other chemicals. The aerosol is inhaled into the lungs where the nicotine and chemicals cross over into the bloodstream.The earliest vape devices looked like cigarettes. With Americans puffing less each year, the cigarette industry sees ESDs and other smokeless products as financial saviors. E-cigarette sales tripled between 2012 and 2013 rising from $500 million to over $1.5 billion and are expected to soon exceed the sales of traditional cigarettes, motivating giant tobacco and other non-cigarette companies to market this product.
In the case of the enzymatic reaction, the two substrates (reactants) are again acetic ester and H2O, the two products of the reaction are alcohol and acetate. Once the acetate group is removed from the cellulose chain, the polymer can be readily degraded by cellulase, which is another enzyme found in fungi, bacteria, and protozoans. Cellulases break down the cellulose molecule into monosaccharides ("simple sugars") such as beta-glucose, or shorter polysaccharides and oligosaccharides. Discarded cigarette filters usually end up in the water system through drainage ditches and are transported by rivers and other waterways to the ocean.
To date, no e-cigarette product has been approved by the FDA for smoking cessation. In contrast, nicotine replacement therapies (e.g., patch, gum, lozenge) and some prescription medications (i.e., varenicline, bupropion) have been evaluated by the FDA and found to be safe and effective at helping people quit smoking. Manufacturers and sellers of e-cigarettes aggressively target young people.
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 This page may contain information that is outdated and may not reflect current policy or programs.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%.
No amount of nicotine is safe for youth as there may be long-term, damaging effects on learning, memory, attention, behavior problems, and future addiction. Electronic cigarettes or vapes (referred to collectively as ‘e‑cigarettes’) are personal vaping devices where users inhale aerosol rather than smoke. The inhaled aerosol usually contains flavourings, a range of toxic chemicals, and may contain nicotine as well (Department of Health and Aged Care 2023a).
WHO regularly monitors and reviews the evidence on ENDS and health and offers guidance to governments. "Yale physicians have been at the forefront in identifying EVALI cases," Dr. Weiss says. She explains that even before CDC guidelines on treating the illness were released, Yale doctors were successfully treating patients with a combination of antibiotics and steroids. Doctors at Yale Medicine also collaborate with researchers in the fields of tobacco and addiction medicine to provide care for patients with EVALI.
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.
As a non-profit organization, we accept no government or tobacco industry funding. We rely on contributions from individuals, philanthropic foundations, corporations and other non-profit organizations to continue working toward a tobacco-free future. The U.S. Surgeon General declared vaping an epidemic among our youth in 2018. Additional collection points are being added all the time, you can use your postcode to find your nearest vape recycling locations. You can take vapes for recycling to the shop where you buy your replacements or to your local authority household waste recycling centre. Once you have bought the kit, it's been estimated that vaping costs about a third as much as smoking.
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.
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.
Although PG and glycerol are the major components of e-liquids other components have been detected. Of note, the analysis identified formaldehyde, acetaldehyde and acrolein [4], 3 carbonyl compounds with known high toxicity [63,64,65,66,67]. While no information was given regarding formaldehyde and acetaldehyde concentrations, the authors calculated that one puff could result in an acrolein exposure of 0.003–0.015 μg/mL [4]. However, given that e-cigarette units of vaping are not well established, users may puff intermittently throughout the whole day. Thus, assuming 400 to 500 puffs per cartridge, users could be exposed to up to 300 μg of acrolein.
This guide supports health care providers, systems, and communities seeking to prevent vaping. These resources and others are on the AAFP’s Tobacco and Nicotine Prevention and Control webpage. Familydoctor.org, the Academy’s patient-facing web resource, has additional materials on tobacco addiction, the harms of vaping and several related topics. Young adults with family incomes of less than 200% of the federal poverty level also were more likely to use e-cigarettes than those with greater family income.
Vaping may also have specific adverse effects on certain groups, particularly young people. The full magnitude of effects of toxic e-cigarette ingredients may not be known for another three decades. Yale’s Tobacco Center of Regulatory Science received funding support for the study from the National Institute on Drug Abuse, which is part of the National Institutes of Health (U54DA036151), and the Center for Tobacco Products of the FDA.

Electronic nicotine and vapor delivery systems, which include e-cigarettes, vaping pens, e-hookah and similar devices, typically contain nicotine. Some ingredients found in e-cigarettes are considered toxic and there is no regulation of what chemicals e-cigarettes contain or how much nicotine the user is inhaling. These factors could lead to long-term adverse health effects for e-cigarette users and bystanders. This new law will reduce exposure to the potentially dangerous chemicals for e-cigarette users and those around them. Prior to electronic cigarettes being added to the Clean Indoor Air Act, only the smoking of substances containing tobacco, including cigars, cigarettes or pipes, were restricted in public places. While many counties have already banned the use of e-cigarettes in public places, including restaurants, bars and other work places, this bill makes the law consistent across New York State.
Other compounds that have been detected in aerosols include acetamide, a potential human carcinogen [5], and some aldehydes [69], although their levels were minimal. Interestingly, the existence of harmful concentrations of diethylene glycol, a known cytotoxic agent, in e-liquid aerosols is contentious with some studies detecting its presence [4, 68, 70,71,72], and others finding low subtoxic concentrations [73, 74]. In this regard, either it was detected at concentrations that did not exceed the authorised limit [73], or it was absent from the aerosols produced [4, 71, 72]. Only one study revealed its presence at high concentration in a very low number of samples [5]. Nevertheless, its presence above 1 mg/g is not allowed by the FDA [73]. Figure 1 lists the main compounds detected in aerosols derived from humectant heating and their potential damaging effects.
To vape is to inhale vapor created from a liquid heated up inside a device. The devices have many names—vape pens, pod mods, tanks, electronic nicotine delivery devices (ENDS), e-hookahs and e-cigarettes. Most e-cigarettes contain nicotine and their repeated use can lead to nicotine addiction or increase the user's risk of addiction. Some e-cigarette brands contain nicotine salts to mask the harshness of nicotine and make it more palatable. As of 2018, all tobacco products must bear the required nicotine addictiveness warning statement on product packages and advertisements in order to warn consumers about the presence of and addictive nature of nicotine.
The new rules will allow FDA to review the safety of batteries and eventually take action to protect the public. "Diacetyl is a well-known harmful chemical, which, among other things, causes a lung disease called 'popcorn lung,'" says Erika Sward, assistant vice president for national advocacy at the American Lung Association. The Electronic Cigarette Company reserves the right to cancel any sales transaction based on its sole discretion where it reasonably believes the purchaser is purchasing products on behalf of a minor. More commonly known as e-cigs or vape kits, we stock a huge range of vaping hardware, from mouth to lung (MTL) to direct lung (DL). Our range of vape pods is ideal to use with nic salts and high-strength e-liquid.
The cells are also less able to form new vascular tubes and to migrate and participate in wound healing. With a 399.73% increase in retail e-cigarette sales (excluding internet sales and tobacco-specialty stores) from 2015 through 2020, the environmental consequences of e-cigarette waste are enormous. The fourth-generation vaporizers can also be customized and come with different types of heating coils — some intended for vaporizing solids, not liquids. In general, people using e‑cigarettes did not report doing so in order to quit smoking regular tobacco cigarettes. In 2022–2023, only 1 in 5 (21%) people who had ever used e‑cigarettes reported that they first used e‑cigarettes to help them quit smoking (Figure 5). The most common reason people gave for using e‑cigarettes was out of curiosity (58%).
Where e-cigarette flavor restrictions had been in effect for at least a year, sales of cigarette brands favored by adults went up by 10%, while sales of cigarette brands that disproportionately attract underage smokers saw a 20% bump. During the study period, hundreds of localities and seven states restricted or prohibited flavored e-cigarette sales. While these policies did reduce per-capita vape sales, they also substantially boosted cigarette sales. To date, there is no state excise or special tax placed on e-cigarettes. In vaping liquids, nicotine and/or flavouring ingredients are dissolved in a liquid mixture.
Over the years, Evans tried to quit by using the nicotine patch, gum, and even hypnosis. When you stop using it, you can go into withdrawal and feel depressed and crabby. We have lots of detailed vaping guides and blog posts to help new vapers make the transition to vaping. Find everything you need to know about e-liquids, starter kits, and what to expect when switching to vaping. Alternatively, why not speak to one of our customer service advisors? Great for new vapers, disposable vape kits are the simplest way to vape.
All this evidence would suggest that e-cigarettes are potentially less harmful than conventional cigarettes (Fig. 2) [11, 14, 22, 24, 27,28,29]. Importantly, however, most of these studies have investigated only short-term effects [10, 14, 15, 22, 27,28,29, 31, 32], and the long-term effects of e-cigarette consumption on human health are still unclear and require further study. Vapes come in colorful, fun, and unique product designs, along with many flavors, all of which come together as part of the attraction for youth who believe that these products are not addictive and are safe to use. Many users believe vaping will reduce stress, anxiety, and depression.
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.
It acknowledges the wisdom of Elders past and present, and pays respect to all Aboriginal communities of today. Always be considerate when vaping around anyone else, especially people with health conditions like asthma or other respiratory conditions, or people who do not like vaping. But as a precaution, it is best not to vape around babies and children if you can avoid it. Remember, if you have stopped smoking completely you have already achieved a huge step in protecting your health, so don't worry if it takes you a while to stop vaping. You can buy them from specialist vape shops, some pharmacies, supermarkets and other retailers, or from an online vape store.
While their manufacturers say they are an alternative for tobacco smokers who want to avoid inhaling smoke, critics say too little is known about the safety of ESDs because they are not regulated. All tobacco products, including e-cigarettes, pose a risk to the health of the user. Beginning smoking, switching to smoking, or reverting to smoking exposes the user to potentially devastating health effects.
The increasing number of adolescent users and reported deaths in the United States prompted the government to ban the sale of flavoured e-cigarettes in 2020. The difference in opinion worldwide may be due to different restrictions imposed. For example, while no more than 20 ng/mL of nicotine is allowed in the EU, e-liquids with 59 mg/dL are currently available in the United States. Nevertheless, despite the national restrictions, users can easily access foreign or even counterfeit products online. Is there sufficient toxicological data on all the components employed in e-liquids?
It's free of heavy metals, pesticides, solvents, microbes, and fungal toxins. It contains nothing but hemp extract and terpenes (the molecules that give cannabis its piney, citrusy flavors). All of the above meet United States Pharmacopeia standards for purity and quality. Our ultra-simple formula means you know exactly what's going into your lungs when you take a puff of a HELO Air.

Learn more about the symptoms and overall effects of smoking on the body below. For example, in New York and Vermont, vaping is prohibited in all smoke-free venues (like workplaces, bars, restaurants, and gambling facilities) except e-cigarette stores. The makeup of these devices—combined with individual or group vaping patterns—can significantly impact what pollutants get into the air and how many. The program provides participants with tailored advice, cognitive and behavioral coping strategies, and social support to help them quit. Now that ebay is starting to allow sellers like myself to utilize the site again why cant they allow a process to become a pre approved seller for vape products.
To date, FDA has authorized 34 tobacco- and menthol-flavored e-cigarette products and devices. These products have undergone rigorous scientific review, including toxicologic assessments, and have been found by FDA to meet the statutory public health standard. Vaping is often thought of as safer than cigarette smoking, but vaping causes health problems, too.
The review authors conclude that further research could help untangle how vapers’ bodies develop disease. These types of studies, they say, promise to identify early indicators of—and ultimately treatments for—vaping-related disease. While some tout e-cigarettes as a solution to quitting conventional smoking, the truth about relative risks is complicated, says Crotty Alexander, who is a researcher in addition to providing patient care and teaching.
E-cigarette waste is potentially a more serious environmental threat than cigarette butts since e-cigarettes introduce plastic, nicotine salts, heavy metals, lead, mercury, and flammable lithium-ion batteries into waterways, soil, and to wildlife. "Nicotine analogs are currently not subject to the FDA process and have not been studied for their health effects," Jabba said. This data brief dives deeper into rural youth tobacco use in Minnesota.
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.
Researchers in a 2018 study found that cinnamaldehyde (found in cinnamon), o-vanillin (found in vanilla), and pentanedione (found in honey) all had toxic effects on cells. Studies suggest that nicotine-free vaping can irritate the respiratory system, cause cell death, trigger inflammation, and harm blood vessels. The e-liquid comes in a Juul pod or J-pod cartridge, which usually contains nicotine.
Any product that does not submit an application by this deadline must be removed from the marketplace, which if properly enforced, could lead a significantly smaller marketplace. The main component of e-cigarettes is the e-liquid contained in cartridges or tanks. To create an e-liquid, nicotine is extracted from tobacco and mixed with a base (usually propylene glycol), and may also include flavorings, colorings and other chemicals (such as formaldehyde and acrolein, which can cause irreversible lung damage). The American Lung Association is very concerned that we are at risk of losing another generation to tobacco-caused diseases as the result of e-cigarettes.
If you purchase e-cigarettes and nicotine refill products, store them out of reach of your children and pets. With these products, it’s the liquid nicotine that can be dangerous, especially to children. According to the American Academy of Pediatrics, as little as one teaspoon of liquid nicotine can be fatal to a 26-pound child.
Without immediate measures to stop epidemic use of these products, the long-term adverse health effects will increase. Despite their popularity, little is known about their health effects. Some suggest that e-cigarettes likely confer lower risk compared to combustible tobacco cigarettes, because they do not expose users to toxicants produced through combustion. Proponents of e-cigarette use also tout the potential benefits of e-cigarettes as devices that could help combustible tobacco cigarette smokers to quit and thereby reduce tobacco-related health risks. Others are concerned about the exposure to potentially toxic substances contained in e-cigarette emissions, especially in individuals who have never used tobacco products such as youth and young adults.
Truth Initiative forcefully rejects, however, the notion that this requires the further development of a huge commercial market in addictive nicotine products focused on growth and the acquisition of new users, most of whom are youth and young adults. Because the youth e-cigarette crisis in the United States and the youth appeal of flavored e-cigarettes go hand in hand, Truth Initiative strongly supports removing all flavored e-cigarettes from the market, regardless of device type. Based on the evidence already collected, the question shouldn’t be whether e-cigarettes are less dangerous than cigarettes, Christiani says, but whether vaping can be very harmful to health too. "To protect public health, I discourage the use of vaping—even to quit smoking," he stresses.
Watch the UK Health Security Agency's video demonstration on the impact of smoking versus vaping. As of July 1, 2024, 1,061 municipalities, plus 26 states, commonwealths, and territories restrict e-cigarette use in 100% smokefree venues. The Royal Children’s Hospital (RCH) acknowledges the traditional owners of the land on which the RCH is situated, the Wurundjeri people of the Kulin Nation, and we pay our respects to their Elders past and present. Dr. Tan provides care to adults alongside an entire team of lung specialists at Loma Linda University Health.
Nicotine-free e-juice contains a number of potentially toxic chemicals, such as base liquids and flavoring agents. However, based on the experience with cigarettes, similar adverse health effects, including COPD, heart disease, and cancer, can be expected. Finally, a 2017 review of the cardiovascular effects of vaping indicates that e-cigarettes may pose certain risks to the heart and circulatory system, notably for people who already have some form of heart disease.
Freebase nicotine products can be used in refill liquids or in cartridges for closed systems. Because the brain experiences significant development during adolescence, nicotine use during this critical time can rewire the brain which can make it easier for youth to get addicted to other substances due to issues with impulse control. Together, these three categories accounted for almost two thirds of expenditures in 2021. If you or someone you know has had a safety issue with an electronic cigarette (e-cigarette or vape), please report the problem to the Food and Drug Administration (FDA) at the FDA Safety Reporting Portal (hhs.gov). For adults looking to talk to teens about vaping, Live Vape Free is an online program that provides tips, tools, and one-on-one support.
According to the manufacturer, a single JUUL pod contains as much nicotine as a pack of 20 regular cigarettes. Although JUUL is currently the top-selling e-cigarette in the U.S., other e-cigarettes are becoming available that look like USB flash drives. Because of their shape, school teachers, administrators, and parents may not notice students using these devices in school, including in classrooms and bathrooms. Adults who use tobacco and are trying to quit should use proven quit tools, like group or phone counseling, paired with medications or nicotine replacement therapy patches, gum or lozenges. The agency says the sweet flavored e-liquids pose a "serious, well-documented risk" of enticing more young people to pick up a nicotine habit. In 2020, nearly 20% of high school students and almost 5% of middle-school students used e-cigarettes, and almost all of those kids used flavored products, the agency said in court documents.
This mixture is typically made up of propylene glycol and/or glycerol (vegetable glycerin) and other chemicals. Flavouring ingredients include chemicals and blends of chemicals used to make different flavours. Disposable e-cigarettes are not covered by the flavor restrictions imposed by the Food and Drug Administration.
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.
In fact, they are widely used as alimentary and pharmaceutical products [2]. In an analysis of 54 commercially available e-liquids, PG and glycerol were detected in almost all samples at concentrations ranging from 0.4% to 98% (average 57%) and from 0.3% to 95% (average 37%), respectively [35]. According to a 2018 study examining infrequent cannabis smoking in adults, vaping THC produced stronger mind-altering effects than smoking a similar amount of weed. However, nicotine alone is relatively harmless, and switching from daily tobacco smoking to daily e-cigarette use can be an important step for people to stop smoking completely. However, researchers found that only daily e-cigarette use had a statistically significant effect on smoking cessation rates. Research generally accepts that while vaping can harm the lungs and other bodily systems, its impact is much less than tobacco smoking.
Dr Goel praised the central government’s initiatives to discourage tobacco consumption, including establishment of over 429 Tobacco Cessation Centers (TCCs), awareness campaigns, and the National Tobacco Quit Line. More information about youth vaping and CATCH My Breath is available on the program’s website. While the federal purchasing age of tobacco is 21, North Carolina law still lists it as 18, and many vape shops are operating under that age.
It can damage your heart, arteries, and lungs, increasing the risk for heart attack, stroke, and chronic lung disease. E-cigarettes recently surpassed conventional cigarettes as the most commonly used tobacco product among youth.1 It is critical that public health officials and the general public understand the potential risks of using them. The FDA recently approved its first menthol-flavored electronic cigarettes for adult smokers. In contrast to the clear evidence that flavored products fueled the youth e-cigarette epidemic, every major U.S. public health authority – including the U.S. Preventive Services Task Force, the CDC and even the FDA itself – has found there is inadequate evidence to conclude that e-cigarettes are effective at helping smokers quit. E-cigarettes are battery-operated devices used for a type of smoking called vaping.
Others can be refilled with liquid, recharged, and used over and over. Our Board of Health is a leader in protecting people from the dangers of e-cigarettes and vapor products. Vapes contain nicotine and other substances like THC that negatively affect brain development in youth. Nicotine is also highly addictive and can lead to smoking later in life. Vapes are electronic devices designed to deliver vapourised liquids into your lungs when you breathe in.
E-cigarettes have become the most commonly used tobacco product among U.S. and Iowa youth, and their popularity has risen dramatically over the past several years. According to the Iowa Youth Survey (IYS), Iowa 11th-graders were far more likely to use e-cigarettes compared to traditional cigarettes. They also reported increased likelihood in trying e-cigarettes and decreased quit success when compared to cigarettes.
The vape juice in this device is tightly sealed inside its own compartment, with heat-resistant food-grade fibers to wick it up to the heating coil. This reduces the chances of liquid sloshing around inside and causing issues with the battery. There's also a smart chip designed to prevent overheating, making it much less likely that you'll burn yourself or start a fire. I stuck it in the wrist of my sweater, inhaled, and blew out a little cloud of vapor. As recently as May 2019, Juul held a 74.6% share in the U.S. e-cigarette market. That’s when a series of regulatory actions contributed to product-reduction concessions and lower consumer demand.
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.
The cytotoxic and pro-inflammatory effects of different e-cigarette flavouring chemicals were also tested on two human monocytic cell lines—mono mac 6 (MM6) and U937 [86]. Also, all the tested flavours produced significant levels of ROS in a cell-free ROS production assay. Finally, diacetyl, pentanedione, O-vanillin, maltol, coumarin, and CAD induced significant IL-8 secretion from MM6 and U937 monocytes [86]. It should be borne in mind, however, that the concentrations assayed were in the supra-physiological range and it is likely that, once inhaled, these concentrations are not reached in the airway space.
There is no single test for EVALI; it’s what is known as a "diagnosis of exclusion," which means that a doctor will conduct tests to rule out other potential diseases and conditions. The primary risk factor for EVALI is current or previous use of a vaping device. They can look like cigarettes, cigars, pipes, pens, USB flash drives, or may be in other forms. We fund research that explores how risk factors such as smoking, poor nutrition, and lack of physical activity can affect the development of cancer. For instance, 68 people died in an outbreak of vaping-related illness (EVALI) in 2019 and 2020.

"One of the real problems [with] these things is that because of the low quality control, you never quite know what you are getting," he says. Those who support minimal regulation contend that limiting the use of e-cigarettes would encourage more people to smoke conventional cigarettes. Wild WestAs scientists struggle to test the safety of e-cigarettes, the devices are becoming more and more popular among teens and preteens. E-cigarette use among U.S. high school students more than doubled from 4.7 percent in 2011 to 10 percent in 2012, according to recent data from the Centers for Disease Control and Prevention's National Youth Tobacco Survey. At least 160,000 students who had never tried conventional cigarettes puffed on e-cigs.
In addition, the VITA only heats its vape liquid to about 240 degrees Fahrenheit. That's much lower than many other kinds of vapes, so it won't be as rough on your lungs. LUVV also says their products are tested to "safeguard against" harmful byproducts of heating metal and vape fluid. They don't provide much detail to support this claim, though, so take it with a grain of salt. Like HELO, LUVV vapes are free of diacetyl, vitamin E acetate, and nicotine.
The most consistent predictors have been descriptive norms of parents’ and close friends’ smoking, indicating that addressing close network members might be the most effective in interventions [27]. In our study, parental smoking reported by adolescents increased all types of susceptibility when analysed independently. In the multivariate models, it did not have clear associations with S-SN and S-EC among girls.
Whilst long-term health effects are not fully known, we do know that they generate toxic substances, some of which are known to cause cancer and some that increase the risk of heart and lung disorders. Electronic delivery systems have also been linked to a number of physical injuries, including burns from explosions or malfunctions, when the products are not of the expected standard or are tampered with by users. The Preventing Online Sales of E-Cigarettes to Children Act was created in 2019 to reduce children and teens access to online sales of smokeless tobacco products. According to a 2020 study by the Centers for Disease Control and Prevention (CDC), 85% of high school students and 74% of middle school students who used tobacco products in the past 30 days reported using a flavored tobacco product during that time. The electronic cigarette (e-cigarette), for many considered as a safe alternative to conventional cigarettes, has revolutionised the tobacco industry in the last decades.
Be sure to meet all the following terms and conditions when buying or selling e-cigarettes, ENDS, or e-liquids on eBay. These terms and conditions may change over time and it is your responsibility to visit these pages to see if and how it may have changed, so that you can remain compliant. There is no data to show nicotine pouches as a safe or effective way to quit. University Health Center medical experts and Nebraska Medicine certified tobacco treatment specialist Jill Selzle, PA, do not recommend these products. Many providers ask their patients about alcohol, drug use and smoking, yet forget to ask about vaping. Project for Teens is an example of a local outreach program that provides support and education on the dangers of vaping.
E-cigarettes are not safe for youth, young adults, and pregnant women, and can be dangerous for adults who use tobacco products. The novel results for school-level factors indicate that prevention of nicotine use may be supported by facilitating nicotine-free schools through policies and programmes. This may address especially the peer selection processes, which have been observed both in school disengagement and smoking initiation [28, 29]. Further, it may influence the students’ descriptive and injunctive norms, which both predict smoking initiation among youth [27].
He also highlighted the ban on e-cigarettes in India under the Prohibition of Electronic Cigarettes Act, 2019, aimed at preventing health risks and curbing their use among youth. These ingredients pose significant health risks, particularly to pregnant women, children, and adolescents, and leads to issues like impaired brain development and respiratory diseases, said Dr Goel. Cumberland County Schools is implementing a national vaping and nicotine prevention program in each of its middle and high schools to try and curb rates of youth vaping. Cigarettes pushed me back to shivering outside the bar where a nicotine habit belongs.
Enter e-cigarettes, which were new, high-tech, and came with no proven health risks. There were no long-term studies yet, but common sense dictated that if you wanted to quit inhaling tobacco through smoking, the least you could do was switch to e-cigarettes. She added that there is also an "absence of studies" on the effects and dosage of nicotine replacement therapy, or NRT, for adolescents as a way to help them quit vaping. Nicotine replacement therapy is the family of medications used to help adults quit using nicotine, including over-the-counter patches, gums or lozenges or prescription inhalers or nasal sprays. California has some of the strictest regulations in the US, including a ban on the sale of flavored tobacco products to residents of any age.
A Foundation-led study presented at the 2024 Society for Research on Nicotine and Tobacco annual meeting found that monthly e-cigarette sales in California declined by 41% after statewide restrictions on the sale of flavored tobacco products took effect. However, the report also noted that the tobacco industry continues to market products to offset these declines, including non-menthol cigarettes that contain other cooling chemicals. Continuing to monitor flavored tobacco product sales is key to assessing policies like these and informing further policy development and implementation. Toxicity is not the only factor in considering risk to an individual or a population from exposure to ENDS emissions.
However, 87% of people who reported using e‑cigarettes with nicotine had obtained them without prescriptions. "This relatively small study showed that e-cigarettes have the potential to decrease heart muscle blood supply, not just under the stress of exercise like traditional cigarettes but even at rest," he says. The authors of a 2019 review point out that e-liquid aerosols contain particulates, oxidizing agents, aldehydes, and nicotine. When inhaled, these aerosols most likely affect the heart and circulatory system. Of note, another study indicated that although RANTES/CCL5 and CCR1 mRNA were upregulated in flavour/nicotine-containing e-cigarette users, vaping flavour and nicotine-less e-cigarettes did not significantly dysregulate cytokine and inflammasome activation [43].
Their actions should come as no surprise as e-cigarette manufacturers fail to provide consumers with guidance or take responsibility for appropriate disposal methods. In a separate study conducted by Truth Initiative in 2019, almost half (46.9%) of e-cigarette device owners said that the e-cigarette device they used currently did not provide any disposal information, such as where to send used batteries or empty pods. Additionally, when e-cigarette device owners were asked about e-cigarette waste disposal, the majority (73.7%) believed that it was difficult to find e-cigarette drop off sites. Principal investigator Wendy Max, PhD, director of the Institute for Health & Aging, noted that from 2013 to 2018, e-cigarette use among high school students soared from 4.5% to 20.8%. The Australian Government’s new Public Health (Tobacco and Other Products) legislation commences from April 2024 and incorporates new controls governing the advertising and promotion of e‑cigarettes (Department of Health and Aged Care 2024). According to the National Tobacco Strategy 2023–2030 (Department of Health and Aged Care 2023b), strengthening regulations on e‑cigarettes has been listed as a priority area, and actions such as prohibiting the sale of flavoured e‑cigarettes have been proposed.
In response to this issue, the PACT Act Amendment prohibits sellers from using the U.S. Post Office to ship e-cigarettes, vapes, flavored and smokeless tobacco products. The PACT Act applies to all shipments in interstate commerce (15 U.S.C. § 376) as well as to all delivery sales. Some people who smoke choose to use both cigarettes and e-cigarettes at the same time on an ongoing basis, whether they are trying to quit or not.
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.
Smoking is the leading cause of lung cancer, and people who smoke are 20 times more likely than nonsmokers to be diagnosed with lung cancer. Tobacco products contain unsafe substances, from acetone and tar to nicotine and carbon monoxide. The inhaled substances can affect your lungs and the other organs in your body.
A 2019 randomized control study also found that daily e-cigarette use leads to an almost doubled rate of smoking abstinence than other nicotine-replacement products after one year. Vaping involves breathing in an aerosol that contains several chemicals, including nicotine and flavoring, through an e-cigarette or vape. SAMHSA's mission is to lead public health and service delivery efforts that promote mental health, prevent substance misuse, and provide treatments and supports to foster recovery while ensuring equitable access and better outcomes.
Levels below the LOD or LOQ, or even below the threshold levels proposed by the AFNOR standard guidelines, provide evidence of the optimal operation conditions (e.g., adequate wick saturation without extreme coil heating) of the ceramic wick-based device. E-cigarettes are battery-powered devices designed to deliver nicotine and/or other substances including, in some cases, flavourings. Although e-cigarettes were first proposed in 1927 by Joseph Robinson1, it was only in the early 2000s that the 1st generation of e-cigarettes or ‘cig-a-likes’ became commercially available2,3,4. Subsequent generations of devices have evolved since then, ranging from e-cigarettes with prefilled or refillable cartridges (2nd generation) to rechargeable tank-style devices (3rd generation) with modifiable or ‘‘Mods’’ components3,4,5,6. The 4th generation of devices, known as ‘Pods’, has been driven by advances in electronic atomization technology3,7,8,9.
A 2016 study found that people who use or have used e-cigarettes are less likely to stop smoking altogether. Flavors vary widely, from "traditional" and menthol to watermelon and "lava flow." Some e-cigarettes taste like traditional cigarettes and even mimic the tastes of specific brands. When the user sucks on the mouthpiece, the heating element vaporizes the solution, which the person then "vapes," or inhales. The nicotine content of the liquid can range from "very high" to zero. Refills come in flavors such as cool cucumber, mango, and mint, which may seem natural and harmless, but a single JUUL refill contains as much nicotine as a pack of 20 cigarettes. To inform this work and evaluate the effectiveness of policy, the CDC Foundation is collecting and analyzing information about e-cigarette sales, teen e-cigarette use, and teens’ attitudes about the epidemic.
Though not all flavors have yet been scientifically studied, there is a strong chance others may also be harmful. We work with community partners to raise awareness of the harms of e-cigarettes and vaping and flavored tobacco products that attract youth, through the Unhyped and CounterBalance campaigns. We also review and share e-cigarette use data and trends and tailor our education efforts accordingly. Learn more about potential health hazards of secondhand aerosol (a.k.a. vapor) emitted by electronic cigarettes and electronic smoking devices.
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. E-cigarettes have been sold in the U.S. since 2007 but in recent years their potential benefits for smokers have been overshadowed by their use by adolescents and teens. Vaping nicotine has not been thoroughly evaluated in scientific studies. For now, not enough data exists on the safety of e-cigarettes, how the health effects compare to traditional cigarettes, and if they are helpful for people trying to quit smoking.
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.
The liquid solution can contain nicotine, flavorings, harmful chemicals, or other substances. Since the early 2000s TTCs have developed interests in e-cigarettes (also known as electronic delivery systems, or ENDS), heated tobacco products (HTPs), snus and nicotine pouches. Companies have referred to these types of product as ‘next generation products’ (NGPs) although terminology changes over time. Finally, the report discusses steps that e-cigarette companies took in 2021 to deter or prevent underage consumers from visiting their websites, signing up for mailing lists and loyalty programs, or buying e-cigarette products online. These steps include the use of online self-certification to verify users were at least 21 years old and following state laws requiring an adult signature upon delivery of e-cigarette products. The 2021 report also provides details on some characteristics of e-cigarette products, including flavors and nicotine concentration, as well as the bundling of the components in cartridge systems.
E-cigarettes consist of a mouthpiece, an e-liquid chamber, an atomiser and a battery. The atomiser has a wicking material that draws the e-liquid onto a battery-powered heating coil. Optimal vapour production depends on an efficient supply of e-liquid to the heating coil, which is limited by the wicking and rate of e-liquid evaporation10,11,12. Power levels that produce aerosol beyond the ability of the wick to resupply the liquid to the coil may result in overheating of the atomizer coil and consequently overheating of the e-liquid10,11. Different types of wicking material, varying in size and shape, have been used in e-cigarettes3,13.
While smoking can increase your risk of certain health conditions over years, like glaucoma, cancer, and issues with blood clotting, some of the bodily effects happen immediately. There's a lot that's still unknown about the harms of secondhand vaping, but research suggests that bystanders who breathe in the aerosol might be exposed to toxins. It's unclear how exposure to these toxins might impact health, but it's possible that repeated exposure could impact lung function in the long term.
Aug. 9, 2023, News Staff — New CDC data suggest that e-cigarette use is becoming more popular among young adults, even as their use of tobacco decreases. Freebase nicotine is nicotine that has been dissolved in a liquid mixture, typically propylene glycol and/or vegetable glycerin, and other chemicals such as flavouring ingredients. E-cigarettes contain nicotine and lithium batteries, making them hazardous waste.
The results showed that people who used e-cigarettes at any point were 19% more likely to develop heart failure compared with people who had never used e-cigarettes. In calculating this difference, researchers accounted for a variety of demographic and socioeconomic factors, other heart disease risk factors and participants’ past and current use of other substances, including alcohol and tobacco products. The researchers also found no evidence that participants’ age, sex or smoking status modified the relationship between e-cigarettes and heart failure. While teen smoking has fallen by 80% over the past 20 years, a new generation is now at risk of becoming addicted to nicotine — and possibly at risk for other serious health problems — through e-cigarettes. More than 2.5 million U.S. middle and high school students are now using e-cigarettes, with nearly 85% of them using flavored products.
I never kidded myself into thinking that this habit was harmless, but my conviction that they were less harmful than cigarettes made the endeavor seem worthwhile, even praiseworthy. A May analysis found that vaping increases the risk of asthma by 200 percent and previous studies have linked the products to lung cancer, respiratory conditions, lung disease and organ damage. It’s still not clear how the toxins found in vaping can affect the health of non-vapers, especially long-term. The limited research available so far has largely focused on immediate health effects.
For detailed, up to date information at country level, see the searchable database on the Tobacco Control Laws website, published by the Campaign for Tobacco Free Kids (CTFK). Regulation of e-cigarettes varies widely across the world, from full bans (e.g. India); only being available on prescription (e.g. Australia); and to being freely sold as a consumer good (e.g. Europe, US). There's no specific antidote for nicotine poisoning, but medical professionals can provide medications to help support patients experiencing more serious symptoms of nicotine poisoning. The American College of Cardiology (ACC) is the global leader in transforming cardiovascular care and improving heart health for all. The Resources section provides links to helpful information, including law and regulation information, guides, publications, special notices, and access to assistance from our customer service representatives.
Among other things, the law prohibits the sale of vapor products to people under 18 years of age, requires sellers to obtain a license, and requires that vapor products in stores are inaccessible to minors. Effective January 1, 2020, the legal sales age of tobacco and vapor products will change to 21. Learn more about the vapor product regulations at the Washington State Liquor and Cannabis Board. E-cigarettes are hooking a new generation on nicotine – putting millions of kids at risk and threatening decades of progress in reducing youth tobacco use. It’s a nationwide crisis of youth addiction, fueled by thousands of kid-friendly flavors and massive doses of nicotine. While secondhand smoke from cigarettes causes serious harm to others, there is no evidence so far that vaping is harmful to people around you and any risks are likely to be very low.
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.
The FDA must act without further delay to remove all flavored e-cigarettes from the market. CDC recommends you not use e-cigarettes or vapor products, especially those with THC. Fewer Pierce County youth are smoking cigarettes in recent years, but more are vaping. The main ingredient in vapes is propylene glycol, vegetable glycerine or glycerol, and almost all vapes contain nicotine, flavours and other chemicals.
To inform schools of intervention needs, the susceptibility measure could be utilized in school surveys and relevant student services as a screening tool. Simultaneously, it would support the evaluation of existing policies and programmes and monitoring of potential counter-effects. For example, an earlier study observed that school-based programmes and policies had resulted in higher susceptibility risk at some intervention schools [37]. Effective and non-counter-productive interventions are especially important for products where susceptibility is at a high level, like e-cigarettes. Interventions to reduce susceptibility therefore need to address product regulation and marketing as well as social influence, norms, and perceptions.
Most of the harmful chemicals in tobacco smoke, including tar and carbon monoxide, are not contained in vape aerosol. Switching to vaping significantly reduces your exposure to toxins that can cause cancer, lung disease, and diseases of the heart and circulation like heart attack and stroke. These diseases are not caused by nicotine, which is relatively harmless to health.
Since ditching e-cigarettes for cigarettes, I’m back to smoking on weekends only. I couldn’t do cardio to save my life; walking up stairs sucked the wind out of me. My stamina and day-to-day life was vastly more affected by this vaping habit than when I used to just smoke a few cigarettes on Saturday nights. Firstly that propylene glycol, largely responsible for making your breath look like a cloud of mist, is also found in fog machines used in concerts and has been linked to chronic lung problems among stagehands. It’s actually FDA-approved for use in food (believe it or not it’s common in pre-made cake mix) but when heated to vaping temperature it can produce the carcinogen formaldehyde. "Furthermore, the US Food and Drug Administration has not approved NRTs for anyone younger than 18 years (although many health care professionals prescribe NRTs for adolescents, as is recommended by the American Academy of Pediatrics).
E-cigarette companies also take advantage of other marketing outlets, including the internet, retail environments, and recreational venues and events. This resource presents an overview of key aspects of e-cigarettes, including health effects, marketing practices, and regulations based on research and evidence available at the time of publication. Since the sixties, cigarette companies, starting with Philip Morris, have freebased nicotine using ammonia, which liberates the nicotine so that it can be speedily absorbed into the lungs and the brain.
While there appears to be some consensus that vaping may be less harmful to health than tobacco cigarette smoking, the dangers of e-cigarettes remain unclear. The range of e-liquid flavours available to consumers is extensive and is used to attract both current smokers and new e-cigarette users, which is a growing public health concern [6]. In fact, over 5 million middle- and high-school students were current users of e-cigarettes in 2019 [75], and appealing flavours have been identified as the primary reason for e-cigarette consumption in 81% of young users [76]. Since 2016, the FDA regulates the flavours used in the e-cigarette market and has recently published an enforcement policy on unauthorised flavours, including fruit and mint flavours, which are more appealing to young users [77].
The harms of e-cigarette use in young people include not only the deleterious effects of nicotine, but also exposure of the lungs and airways to potentially toxic solvents and flavoring chemicals. The rapidly rising rates of use in young people and the high rates of daily use strongly suggest that many are addicted to nicotine and will have difficulty in stopping use of all tobacco products. One study found that people who use only e-cigarettes increase their risk of developing lung disease by about 30% compared with nonusers. Electronic cigarettes (e-cigarettes) and other vapor products are devices used to heat and aerosolize (turn into particles) highly addictive nicotine or other substances that a person can inhale into their lungs.
