To learn more about tobacco and its health effects, see Tobacco and Cancer. There have been reports of e-cigarettes exploding and causing serious injuries. 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.
"Parents should base their information on accurate facts and also encourage their children to read about and understand the science on this issue instead of relying on what their friends and peers tell them." Oregon Health & Science University is dedicated to improving the health and quality of life for all Oregonians through excellence, innovation and leadership in health care, education and research. Food and Drug Administration (FDA) has regulatory authority over synthetic nicotine as it does over tobacco-derived nicotine.
However, within the adult demographic, 12.7 percent of 18- to 24-year-old adults and 21.3 percent of males, ages 18-24, are "current users" of e-cigarettes. The e-cigarette device (Vype ePod1.0, Nicoventures Trading Ltd., Blackburn, UK) consists of a metallic outer device case, a printed circuit board to control the device, a lithium-ion rechargeable battery (350 mAh) and an e-cigarette cartridge (Fig. 1). The voltage ranges from 2.2 to 3.1 V and is not adjustable by the user. The device has dimensions (h × w × d) of 104.2 × 19.1 × 10.5 mm and a power output of 6.5 ± 0.5 W. The cartridges or pods consist of a plastic case holding the ceramic wick material and a flat metal heating element (NiCr, 0.8 –1.4-Ω resistance). Each pod is pre-filled with Vype e-liquid (1.9 mL) and is magnetically attached to the device.
They found that kids who used e-cigs were more likely than non-users to smoke cigarettes or other tobacco products over the next year. To study the short-term impacts of vaping, the researchers performed MRI exams on 31 healthy, non-smoking adults before and after vaping a nicotine-free e-cigarette. Comparing the pre- and post-MRI data, the single episode of vaping resulted in reduced blood flow and impaired endothelial function in the large (femoral) artery that supplies blood to the thigh and leg. The endothelium, which lines the inside surface of blood vessels, is essential to proper blood circulation. Once the endothelium is damaged, arteries thicken, and blood flow to the heart and the brain can be cut off, resulting in heart attack or stroke.
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.
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.
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.
Little research has been conducted into the safety of e-cigarettes and e-liquids in pregnancy. It is not known whether the vapour is harmful to a baby in pregnancy. E-cigarettes do not produce tar or carbon monoxide, two of the most harmful elements in tobacco smoke.
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.
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.
Much like free-base nicotine products, these liquids contain propylene glycol and/or vegetable glycerin, as well as other chemicals such as flavouring ingredients. Most vaping devices use electrical power from a battery to heat a liquid solution. The term "vaping" is also used to refer to the inhalation of cannabis aerosols, which are produced by products that differ from nicotine products described on this page. Propylene glycol and glycerin are the most common solvents used in vapor products. While generally recognized as safe for ingestion by the FDA, research has found both substances to be toxic when aerosolized through the vaping process.
Research on health effects of secondhand exposure to e-cigarettes is still emerging. The quantity of these carcinogens is less that what is found in conventional cigarettes. While some young people may be able to quit e-cigarette use on their own, others, particularly daily users, are likely to find this to be very difficult.
Rates of e-cigarette use among Cumberland students aren’t available, but across North Carolina, 21.4% of high school respondents to the state’s 2023 Youth Risk Behavior Survey said they currently vaped. The state’s rates are significantly higher than the national rates of 10% for high schoolers and 4.6% of middle schoolers, according to the National Youth Tobacco Survey. The combo could raise your odds for lung cancer even higher, new research warns. But now that I’ve gotten rid of the endless, all-day vaping, and a nicotine hit makes me stink like a dive bar ashtray, makes my mouth taste like dirt, and makes my friends recoil from my presence, I’ve got reasons to cut back.
Separate studies have shown that newer e-cigarettes may deliver higher doses of nicotine more efficiently, which could explain the recent findings. The investigators acknowledged that more frequent use of e-cigarettes may also reflect greater determination to quit smoking combustible cigarettes. They noted that their study did not evaluate the risks of youth e-cigarette use. E-cigarettes are the most commonly used commercial tobacco product among youth,1 so it is critical that public health officials and the general public understand the potential risks of using them.
And using overly high temperatures could increase the stress on your lungs. Long-term users may not want to keep buying new vapes every time, though, as we touch on in our article on the best 0 nicotine rechargeable vapes. If you're not using disposables, the next safest option is a closed-system vape.
The survey also found that Minnesota youth are ill-informed about the health risks of e-cigarettes with 76.1% of 11th graders saying there is either no, slight, or a moderate risk to using e-cigarettes. 11th grade students responding to the student survey said that the top ways they got e-cigarettes included getting products from friends (72.3%), getting products at a vape shop (14.0%), and on the Internet (9.6%). Among 8th grade students, e-cigarette use nearly doubled from 2016 to 2019, and one in four 11th graders now use e-cigarettes. Students in all grades surveyed now use e-cigarettes and vapes at five times the rate of conventional cigarettes. In Australia, during the survey period, it was not legal to obtain e‑cigarettes containing nicotine without a prescription (TGA 2020).
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.
That means you don't have to worry at all about the effects of hot vapor in your lungs. Part of the appeal of vaping is that it can help you quit smoking little by little instead of going cold turkey. These small disposables from Elf Bar make that easier by reducing the amount of nicotine per inhale. While many inhalers use e-liquid containing 5% nicotine salt, the ELFBAR 600 lets you choose between 2%, 1%, and 0%. It's a great way to gradually wean yourself off this addictive chemical. More and more people are vaping cannabidiol, or CBD, to feel the relaxing effects of cannabis without the intoxication.
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.
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).
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.
Because there is no safe tobacco product, quitting use of all tobacco products is the best way to protect your health. Most e-cigarettes contain nicotine, which is highly addictive and can harm adolescent brain development, which continues into the early to mid-20s. E-cigarettes can contain other harmful substances, including cancer-causing chemicals; chemicals linked to serious lung disease; and heavy metals, such as nickel, tin, and lead. Young people who use e-cigarettes may be more likely to smoke traditional cigarettes in the future. Vapor products produce aerosol by heating a liquid solution, which is inhaled as an aerosol. The process is referred to as "vaping." Vapor products often contain nicotine.
Electronic nicotine dispensing systems (ENDS), commonly known as electronic cigarettes or e-cigarettes, have been popularly considered a less harmful alternative to conventional cigarette smoking since they first appeared on the market more than a decade ago. Both the electronic devices and the different e-liquids are easily available in shops or online stores. The long-term health effects of electronic cigarettes (e-cigarettes) are not fully understood, but the science indicates they are not a safe alternative to smoking. Most are noncombustible which includes a battery, a heating element, and a liquid compartment, usually containing addictive nicotine, that is added to the e-liquid or included in the device. The heating element aerosolizes the liquid for the inhalation of the liquid nicotine or other contents.
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.
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.
Dual use, which is common, is at least as dangerous and likely more dangerous than smoking conventional cigarettes or using e-cigarettes alone. Further, not all ENDS are the same and the risks to health may differ from one product to another, and from user to user. E-cigarettes are still fairly new, and more research is needed over a longer period of time to know what the long-term effects may be.
However, we do allow certain pre-approved sellers to list e-cigarettes, Electronic Nicotine Delivery Systems (ENDS), and e-liquids on the US eBay website (eBay.com) provided they follow federal, state, local, and other applicable laws and regulations. This policy is applicable to those approved sellers, and buyers who transact with them.

Last year, 9.4% of individuals ages 12 years and above reported vaping nicotine within the previous month, up from 8.3% in 2022. "This research has provided greater understanding in the court systems nationwide as to the nature of drug usage, abuse, and overdose cases in which electronic cigarettes were used to deliver an illicit drug," the researchers concluded. THC, synthetic cannabinoids, and dextromethorphan, a drug found in some cough medicines, "were identified in e-liquids purportedly containing only CBD to be consumed for ‘health benefits,’" the researchers said. Results from the National Drug Strategy Household Survey do not provide evidence for or against the use of e-cigarettes as a smoking cessation tool, or as a gateway to tobacco smoking. The age groups most likely to smoke tobacco in 2019 and 2022–2023 were the least likely to use e-cigarettes, and the age groups most likely to use e-cigarettes had low tobacco smoking rates in 2019 and 2022–2023. In 2022–2023, 1 in 5 (19.8%) people aged 14 and over in Australia reported having used e‑cigarettes at least once in their lifetime, with 7% currently using e‑cigarettes at least daily, weekly, monthly, or less often than monthly.
Research has also shown flavor chemicals to be toxic in both e-liquid and aerosol form. While many flavor chemicals used in vaping products have been approved for ingestion, they have not yet been tested for safety when aerosolized. Flavor chemicals are typically not listed on e-cigarette packaging, and most e-liquids contain more than one flavor chemical. Benzaldehyde (used in cherry-flavored products) and 2, 5-dimethyprazine (used in chocolate-flavored products), specifically, may harm human health.
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.
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].
It may also increase the risk of developing mood disorders and problems with impulse control. They appeared on the U.S. market in 2015 and are now the top-selling brand of e-cigarette in the country. Although secondhand vapor may not affect the lungs the same way as vaping, it is better to avoid it, if possible. E-cigarettes have been strongly linked to continued tobacco use and are not recommended for young people.
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.
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.
Despite the general decline in smoking, it remains more prevalent among youth with lower socio-economic position (SEP). This has been observed with family-level SEP indicators, including parental education [3, 4] and family affluence [5]as well as individual-level indicators of adulthood SEP such as academic performance [4, 5] and vocational education [6–8]. For smokeless tobacco (snus) use and electronic cigarette (e-cigarette) use, the associations with SEP have been mixed [7, 9, 10]. The scientists investigated the effect of the e-liquids on cells called endothelial cells that line the interior of blood vessels.
Krishnan-Sarin points to progress that has been made—finally—in recent years to reduce regular cigarette smoking rates among young adults. In her opinion, the significant decline is due to the success of large-scale public health campaigns and a general awareness among youth that cigarettes are harmful to health. The liquid they contain also has many monikers—it might be called e-juice, e-liquid, cartridges, pods, or oil.
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.
E-cigarettes are devices that allow you to inhale nicotine in a vapor rather than smoke. Vaping is often pushed as a healthier alternative to smoking and used as a tool to get smokers to quit, which could have contributed to the state's high vaping rate. The findings come as damning research mounts on the harms of e-cigarettes, particularly in young people, including irreversible lung damage and even cancer. Smoking can lead to ongoing complications and long-term effects on your body systems.
Strong decisive action is needed to prevent the uptake of e-cigarettes based on the growing body of evidence of its use by children and adolescents and health harms. Public Health Consequences of E-Cigarettes reviews and critically assesses the state of the emerging evidence about e-cigarettes and health. This report makes recommendations for the improvement of this research and highlights gaps that are a priority for future research. Vape explosions have been linked to faulty batteries in vaping devices.
This is why it took as long as it did for the negative health effects of cigarettes to be widely recognized. There is abundant evidence that e-cigarettes can help some individuals to quit smoking, so they should be more widely recommended as smoking cessation aids. Vaping and smoking share similar negative effects on the body, such as damage to the lungs and increased cancer risk.
Taken together, the studies provide strong evidence that an interactive, tailored text message program can help teens and their older peers break free from nicotine addiction. These findings are especially important given the recent youth mental health crisis documented by the U.S. Adolescents in this study were characterized by high severity of past-year problems with depression, sleep, anxiety, trauma, and substance use. In addition, moderate to high levels of nicotine dependence were observed across multiple measures, with more than three-quarters (76.2%) of teens vaping within 30 minutes of waking — a common way to measure addiction. Harvard T.H. Chan School of Public Health brings together dedicated experts from many disciplines to educate new generations of global health leaders and produce powerful ideas that improve the lives and health of people everywhere. Each year, more than 400 faculty members at Harvard Chan School teach 1,000-plus full-time students from around the world and train thousands more through online and executive education courses.
Vaping has exploded into a national crisis, and tobacco companies are helping to fuel it by targeting kids with flavors such as gummy bear and cotton candy. E-cigarette companies have promoted unsubstantiated health claims about their products as healthier than traditional cigarettes, when, in fact, e-cigarettes are uniquely dangerous for kids due to nicotine’s impact on their developing brains. Since being introduced to the U.S. market in 2007, e-cigarette use among youth has increased to epidemic levels (Surgeon General's Advisory on E-cigarette Use Among Youth, 2018). The availability of flavored e-cigarettes is one of the most commonly cited reasons for e-cigarette use among youth (Tsai et al., 2018). Given the importance of flavors contributing to use of e-cigarettes among youth, these data briefs build on this previously published article, providing an update on trends in unit sales of e-cigarettes in the U.S. by product and flavor type.
They do contain propylene glycol, but the concentrations are far below levels usually considered harmful. Though this might make the VITAs hit slightly harsher than vapes without this ingredient, it shouldn't pose much risk to your health. But levels are usually low and generally far lower than in tobacco cigarettes. I don’t sit around inhaling lungful after lungful of vape for seven minutes at a time, like I would a real cigarette, so the lingering aura from my habit certainly isn’t hovering for extended periods of time.
Participants took one vape from an e-cigarette, with at least 12 mg/mL of nicotine, or inhaled a conventional cigarette, every 20 s for 10 min. Blood samples were collected 1, 2, 4, 6, 8, 10, 12 and 15 min after the first puff, and nicotine serum levels were measured by liquid chromatography-mass spectrometry (LC–MS). The results revealed higher serum levels of nicotine in the conventional CS group than in the e-cigarette group (25.9 ± 16.7 ng/mL vs. 11.5 ± 9.8 ng/mL). However, e-cigarettes containing 20 mg/mL of nicotine are more equivalent to normal cigarettes, based on the delivery of approximately 1 mg of nicotine every 5 min [40].
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).
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.
If you’re having trouble quitting e-cigarettes on your own, get help from your doctor or from other support services, such as your state quitline (1-800-QUIT-NOW) or the American Cancer Society (1-800-ACS-2345). Electronic cigarettes (e-cigarettes) are sometimes called e-cigs, vapes, vape pens, and electronic nicotine delivery systems (ENDS). Get the facts about e-cigarettes, their health effects, and the risks of vaping.
Yet another analysis linked e-cig use with greater odds of trying tobacco. They come in kid-friendly flavors, including chocolate, bubble gum and gummy bear. Sold online and in the mall, e-cigarettes are also easy for minors to acquire.
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.
For information about ENDS products that are authorized for marketing in the U.S., view FDA’s "Searchable Tobacco Products Database." These problems can seriously hurt the person using the ENDS product and others around them. There may be added dangers, for example if a vape battery catches fire near an oxygen tank, a propane tank (such as used in backyard grills), or a gas pump, or if a person has a vape-related seizure while driving.

Reynolds’ Velo nicotine pouches, while holding just a 1.2% market share, has had a 25.8% year over year sales growth, as well as up 96.7% for the four-week period. Nicotine pouches have a 5.1% market share with sales up 73.4% over the year. Dr Goel underscored the importance of dispelling misinformation and promoting evidence-based approaches to tobacco cessation.
Vaping can cause breathing problems, organ damage, addiction and other conditions. Lots of people want to know about the health effects of e-cigarettes. They’re still a relatively new product, so it’s too soon to know for sure. This is because e-cigarettes don’t contain cancer-causing tobacco, and most of the toxic chemicals found in cigarettes are not in e-cigarettes. High rates of vaping are "especially concerning given the rate of youth and young adults using these products," she said in a university news release.
However, this is still one of the safest vape-like devices on the market. Overall, it's one of the best no nicotine vapes on the market for health conscious users. Because vaping is far less harmful than smoking, your health could benefit from switching from smoking to vaping. They can cause side effects such as throat and mouth irritation, headache, cough and feeling sick.
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.
However, the leading causes of nicotine poisoning are smokeless tobacco products (chew and snuff) and liquid nicotine that’s used in e-cigarettes. Chewing and snorting tobacco releases more nicotine into the body than smoking. E-cigarettes are not completely risk free but when compared to smoking, evidence shows they carry just a fraction of the harm. The problem is people increasingly think they are at least as harmful and this may be keeping millions of smokers from quitting. Local stop smoking services should look to support e-cigarette users in their journey to quitting completely.
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.
Some products claiming to be nicotine-free (ENNDS) have been found to contain nicotine. Your doctor will begin his or her diagnosis by asking you about your use of e-cigarettes within the past three months and whether you vaped a product containing nicotine, THC, or both. During the physical exam, your doctor will use a stethoscope to listen to your lungs, check your heartrate, and measure your blood oxygen saturation using a pulse oximeter. A chest X-ray or computed tomography (CT) scan is usually necessary for diagnosis and will show hazy looking spots (called opacities) in the lungs. Your doctor may also order bloodwork to rule out other possible causes of your illness.
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.
Set firm expectations that they do not use any type of commercial tobacco product, including e-cigarettes and vapes. For more guidance, here's a tip sheet for talking to your children about e-cigarettes. Electronic smoking devices (ESDs) do not just emit "harmless water vapor." Secondhand aerosol (incorrectly called vapor by the industry) from ESDs contains nicotine, ultrafine particles and low levels of toxins that are known to cause cancer.
In this latter regard, no differences were encountered in the frequency of tumour appearance in rats subjected to long-term (2 years) inhalation of nicotine when compared with control rats [48]. Despite the lack of carcinogenicity evidence, it has been reported that nicotine promotes tumour cell survival by decreasing apoptosis and increasing proliferation [49], indicating that it may work as a "tumour enhancer". In a very recent study, chronic administration of nicotine to mice (1 mg/kg every 3 days for a 60-day period) enhanced brain metastasis by skewing the polarity of M2 microglia, which increases metastatic tumour growth [50]. Assuming that a conventional cigarette contains 0.172–1.702 mg of nicotine [51], the daily nicotine dose administered to these animals corresponds to 40–400 cigarettes for a 70 kg-adult, which is a dose of an extremely heavy smoker.
Surgeon General’s recommendation urging those who influence youth, young adults and people who are pregnant to discourage nicotine use in any form, including e-cigarettes. To protect kids now, states and cities must also continue their growing efforts to end the sale of flavored e-cigarettes, as well as other flavored tobacco products. Electronic cigarettes, or e-cigarettes, are part of a category of products called Electronic Smoking Devices (ESDs), which are designed to mimic combustible tobacco cigarettes and, in most cases, contain varying levels of nicotine. Our compassionate providers can help both you and your child understand the dangers of vaping and provide resources that help people quit using tobacco products like e-cigarettes. During this time, the brain is constantly rewiring itself, which makes it far more vulnerable to nicotine addiction. This is part of why teens who vape are nearly three times more likely to begin smoking cigarettes.
E-cigarettes are popular among teens and young adults, according to the Centers for Disease Control and Prevention (CDC). In 2019, nearly 28 percent of high-school students and 11 percent of middle-school students reported using e-cigarettes. About 8 percent of young adults ages 18 to 24 reported using e-cigarettes in 2018. In 2019, nearly 28% of high-school students and 11% of middle-school students reported using e-cigarettes. E-cigarettes are battery-powered devices that generate an inhalable aerosol that usually contains nicotine. Minnesota teens are using e-cigarettes and vapes at alarming rates, exposing themselves to the harms of nicotine and risking addiction.
E-cigarettes (often called vape pens) are battery-operated vaping devices that heat a liquid until it becomes an aerosol (mist), which is inhaled. It usually contains nicotine, other harmful chemicals, and flavorings. Even e-cigarettes that claim to have no nicotine have been found to contain nicotine. A non-smoker who uses ENDS may become addicted to nicotine and find it difficult to stop using ENDS or become addicted to conventional tobacco products. Further, many e-cigarettes are designed to allow the control of nicotine (which can reach dangerously high levels).
In addition to nicotine, e-cigarettes can also be used to inhale other drugs, such as cannabis. Retailers are not permitted to sell e-cigarettes in retail outlets to anyone. Instances of non-compliance should be reported to the local council where the premises is located. More than 5 million middle and high school students used e-cigarettes, according to the 2019 National Youth Tobacco Study (NYTS), up from more than 3.6 million the previous year. Surgeon General’s office began the work of awareness when the nation’s doctor, Jerome Adams, MD, issued a warning that vaping among youth has reached epidemic levels. This module provides an understanding of the inner workings of e-cigarettes, the content of the aerosols they produce, and thirdhand smoke.
Among girls, only a higher proportion of never-users in the school remained protective for S-SM and S-EC. Among boys, the same was observed for S-EC, whereas a higher proportion of students with positive attitudes towards snus use in one’s age group increased S-SN. Interestingly, a higher proportion of students planning for general upper secondary education had lowered S-EC and S-SN in the univariate analyses but increased S-SM and S-SN in the multivariate models. This may reflect, for instance, more complex interactions between individual- and school-level factors influencing susceptibility among boys. In general, students with positive attitude towards product use in one’s age group and current use of some other tobacco or nicotine product had consistently higher susceptibility regardless of product type.
Some public health experts believe that e-cigarettes are an essential alternative to smoking tobacco that can help smokers quit. Others argue that e-cigarettes could be a route into nicotine addiction and point out that their long-term safety has not yet been proven. There are also those that believe that e-cigarettes may offer public health benefits but that e-cigarettes should be regulated, particularly when it comes to the marketing of such products.
Resources are available to help teens quit through the American Lung Association and SmokeFreeTeen. Several outlets also take a look at the history behind regulation of cigarettes and vaping products and also how the growing anxiety about the outbreak of respiratory problems might be dangerous. Other regions are increasingly playing larger roles in the growing global smoking epidemic. The WHO Eastern Mediterranean Region (EMRO) now has the highest growth rate in the cigarette market, with more than a one-third increase in cigarette consumption since 2000.
The number of unique e-cigarette products more than quadrupled from 453 in June 2021 to 2,023 in June 2022. But it is not responsible for the harmful effects of smoking, and nicotine does not cause cancer. People have safely used nicotine replacement therapy (NRT) to stop smoking for many years. Nicotine replacement therapy is prescribed by doctors or is available from pharmacies. I’m doing my part by not smoking cigarettes and releasing their known carcinogens to the atmosphere, while still dealing with my addiction. I am trying to improve my health, trying to not smell like cigarette smoke all the time, and get to spend time with my loved ones as well.
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.
The data shows that in 2021, 69.2 percent of e-cigarette cartridges either sold or given away contained menthol-flavored e-liquids, and the rest were tobacco-flavored. E-cigarette companies also spent $90.6 million more advertising and promoting their products in 2021 than in 2020. Flavored e-cigarettes are very popular, especially among young people.
In this data brief we use the 2017 MYTS to report e-cigarette initiation prevalence, which teens are trying e-cigarettes, and why initiation is a problem. The tobacco use landscape in the United States and Minnesota is evolving. E-cigarettes are rapidly increasing in popularity, especially among youth. However, products like cigarettes and smokeless tobacco continue to have a stronger hold in rural areas due to decades of targeted marketing by the tobacco industry, which integrated tobacco use into rural culture.
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.
] have been offset by the increasing consumption in low income countries, especially China. The Chinese market now consumes more cigarettes than all other low- and middle-income countries combined. Levels of naphthalene were slightly higher than those of pyrene in e-cigarette emissions, while the respective air blank was lower. Nevertheless, it seems likely that these compounds were detected in e-cigarette emissions due to their presence as low-level contaminants in the background air, rather than originating from the vaping product. E-cigarettes are devices that use an electric battery to heat up a liquid (commonly called an "e-liquid") into an aerosol, which the user inhales. Vitamin E acetate, diacetyl, formaldehyde, and acrolein are just a few among hundreds of potentially hazardous substances commonly found in e-liquids and their aerosols.
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.
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.
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.
Njoy’s products accounted for less than 3% of U.S. e-cigarette sales in the past year, according to retail data from Nielsen. Vuse, owned by Reynolds American, and Juul control about 60% of the market, while hundreds of disposable brands account for the rest. The market share of disposable e-cigarette products increased from 52.0% to 57.8% between 2022 and 2023. Among disposable e-cigarette products, those with flavors other than tobacco accounted for 94.7% of the market in 2023. Research indicates that e-cigarettes may emit harmful substances, which means there could be health risks to the user and others through secondhand exposure. The Texas Tobacco Quitline offers free, confidential, and convenient cessation services to Texas residents ages 13 and older.
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.
If used during pregnancy, nicotine may also cause premature births and low birthweight babies. The use of e-cigarettes is often referred to as "vaping" because many people believe e-cigarettes create a vapor, which is then inhaled. But in fact, e-cigarettes produce an aerosol made up of tiny particles, which is different from a vapor. Some vape shops may have legal responsibilities as both manufacturers and retailers of tobacco products.
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’.
According to Blaha, there are three reasons e-cigarettes may be particularly enticing to young people. Second, e-cigarettes have a lower per-use cost than traditional cigarettes. State and local authorities can restrict the sale of flavored tobacco products, including e-cigarettes.
Below is a brief overview of the different types of vape kits available now. Sign up for free and stay up to date on research advancements, health tips, current health topics, and expertise on managing health. Keep in mind that trying something to beat the urge to use tobacco is always better than doing nothing. And each time you resist a tobacco craving, you're one step closer to being tobacco-free.
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.
In 2017, the campaign began prioritizing e-cigarette prevention messaging to combat increasing youth vaping rates. "The Real Cost" campaign also educates teens on the health consequences of smoking cigarettes. Given that there is no safe tobacco product, youth and adults who do not use tobacco products should not start using e-cigarettes. Vaping and smoking both involve inhaling nicotine and other substances into your lungs. E-cigarettes heat liquid to make an aerosol; cigarettes burn tobacco, which creates smoke.
In e-cigarettes, tobacco combustion is replaced by e-liquid heating, leading some manufacturers to propose that e-cigarettes have less harmful respiratory effects than tobacco consumption. Other innovative features such as the adjustment of nicotine content and the choice of pleasant flavours have won over many users. Nevertheless, the safety of e-cigarette consumption and its potential as a smoking cessation method remain controversial due to limited evidence. Moreover, it has been reported that the heating process itself can lead to the formation of new decomposition compounds of questionable toxicity. Numerous in vivo and in vitro studies have been performed to better understand the impact of these new inhalable compounds on human health.
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. Links to E-Cigarette Resources Links other websites, reports educational materials, toolkits and more information on e-cigarettes.
However, when they looked at other scenarios, such as bar settings where many people were vaping, the researchers found that the concentration of toxins in the air was generally much higher than in residential settings. The more people were vaping and the higher voltages were used, the worse the air quality. In some scenarios, levels of both formaldehyde and acrolein were above OEHHA safety standards for bar employees. This article explains the toxins found in vaping aerosol, the factors affecting secondhand vaping, and potential health effects. MARIE — The Inter-Tribal Council of Michigan has partnered with Truth Initiative to offer a first-of-its-kind free and anonymous text message quit vaping program through the This is Quitting for teens and young adults.
As with high school students, e-cigarette use was much more common than cigarette use. E-cigarettes come in many shapes and sizes and can also be called e-cigs, e-hookahs, vapes, vape pens, personal diffusers or diffuser sticks. But one vape can contain the equivalent of 50 cigarettes of nicotine in the one product. They also contain a complex combination of chemicals including nicotine, nickel, tin, arsenic, chlorine and lead. These substances can be harmful to the body, with different flavourings helping to mask these poisons when they are taken into the body. An electronic cigarette (e-cigarette) is a battery-operated device that heats liquid nicotine, flavoring, and other additives to create an aerosol.
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.
In contrast, other studies found acute microvascular endothelial dysfunction, increased oxidative stress and arterial stiffness in smokers after exposure to e-cigarettes with nicotine, but not after e-cigarettes without nicotine (reviewed in [20]). In women smokers, a study found a significant difference in stiffness after smoking just one tobacco cigarette, but not after use of e-cigarettes (reviewed in [20]). However, research updates on, and analysis of, the potential health benefits/risks of e-cigarettes are outside the scope of TobaccoTactics. These devices come in a variety of shapes and sizes, as pictured below, with several different names. Some e-cigarettes look like regular cigarettes, but many resemble pens or USB flash drives, and are not recognized as tobacco products. Larger e-cigarettes such as tank systems, or "mods," do not resemble other tobacco products.
"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.
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.
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).
According to the 2021 National Youth Tobacco Survey, more than 2 million U.S. middle and high school students reported using e-cigarettes in 2021, with more than 8 in 10 of those youth using flavored e-cigarettes. The mid-to-long-term consequences of e-cigarettes are not yet known, as it's a new product and has been sold for less than a decade in the U.S. While much remains to be determined about these lasting health consequences of these products, we are very troubled by what we see so far. The inhalation of harmful chemicals can cause irreversible lung damage and lung diseases.
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 short, the ingredients in e-cigarette liquid have caused users health problems. The health effects of e-cigarettes are still being studied but nicotine addiction, harmful chemical additives, battery explosions causing injury, acute nicotine poisoning and vaping related lung injury have all been linked to use of e-cigarettes and vaping. An e-cigarette is a battery-operated device that heats liquid into an aerosol that the user inhales. E-cigarettes typically operate on a rechargeable lithium-ion battery.
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.
