Public Health Consequences of E-Cigarettes The National Academies Press
Vapor products have many names, including electronic nicotine delivery systems (ENDS), electronic cigarettes (e-cigarettes), JUULs or vape pens. All adults who smoke conventional cigarettes or other combustible (burned) tobacco products should be advised to quit smoking at the earliest opportunity, recognizing that quitting is hard and often takes repeated, dedicated efforts. Individuals can also seek cessation support by calling QUIT-NOW or ACS-2345.
As vaping is still relatively new, we can’t be sure there aren’t any long-term effects to people who breathe in someone else’s vapour. E-cigarettes should only be used to help you stop smoking, or to stop you going back to tobacco. After using my vape (e-cigarette) for over a year now, my body feels so much better than when I was smoking cigarettes.
You should use the vape as much as you need to manage your cravings and withdrawal symptoms. Here are some of the most common myths, and the facts based on scientific evidence and data. Nicotine itself is not very harmful and has been used safely for many years in medicines to help people stop smoking. E-liquids come in different nicotine strengths, so you control how much nicotine you need to help with cravings and other withdrawal symptoms, such as feeling irritable and having low mood. Electronic cigarettes and ESDs also pose a risk of fire and explosions, which result in serious injuries and property damage.
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 This page may contain information that is outdated and may not reflect current policy or programs.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%.
Many grants on this topic are funded through the Tobacco Regulatory Science Program, an NIH partnership with FDA’s Center for Tobacco Products to fund research to inform FDA’s tobacco regulatory activities. Interestingly, most of these reports linking COVID-19 harmful effects with smoking or vaping, are based on their capability of increasing the expression of angiotensin-converting enzyme 2 (ACE2) in the lung. It is well known that ACE2 is the gate for SARS-CoV-2 entrance to the airways [106] and it is mainly expressed in type 2 alveolar epithelial cells and alveolar macrophages [107]. To date, most of the studies in this field indicate that current smokers have higher expression of ACE2 in the airways (reviewed by [108]) than healthy non-smokers [109, 110]. While tobacco products have been a long-standing public health issue, e-cigarette (aka e-cigs, vape pens, vapes) use has continued to gain popularity throughout the last decade. Poison centers began receiving calls about e-cigarettes and liquid nicotine products in 2010, which overlaps with the initial period where these products reached the U.S. market.
According to the 2023 National Youth Tobacco Survey, more than 2 million teens reported vaping nicotine, and there was an increase in current overall tobacco product use among middle school students (4.5% to 6.6%) and multiple tobacco product use (1.5% to 2.5%). They are not technically categorized as smokeless tobacco, so the Food and Drug Administration (FDA) does not regulate them as strictly as smoked tobacco products or combustible tobacco. Without long-term data, we cannot be certain if or how reduced exposure will prevent harm to one’s health. In Canada, most of the provinces require smokers to be 19 years of age to purchase cigarettes (except for Quebec and the prairie provinces, where the age is 18). However, the minimum age only concerns the purchase of tobacco, not use. Alberta, however, does have a law which prohibits the possession or use of tobacco products by all persons under 18, punishable by a $100 fine.
For those who currently use, My Life My Quit offers resources tailored to support youth ages on their journey to quitting. Youth and teens can text Start My Quit to or visit the website for free, confidential quit help. Other appeals courts have sided with the FDA, which regulates new tobacco products under a 2009 law aimed at curbing youth tobacco use.
A note from Cleveland ClinicNicotine poisoning is on the rise, mostly due to the availability of some of the newer forms of nicotine that are now popular. Children eat cigarettes and can be accidentally poisoned by touching, tasting or swallowing liquid nicotine or liquid nicotine-containing products used in e-cigarettes. To keep you and your family and pets safe from nicotine poisoning, the most effective approach would be to eliminate or ban tobacco-containing or nicotine-containing products in your home. If you're interested in quitting smoking, your healthcare team is here, ready and looking forward to helping you. All tobacco products contain nicotine and are harmful to your health. All are technically capable of causing poisoning if taken in large enough quantities.
Whichever vape you choose, make sure you use it daily to help you make the switch from cigarettes. A vape bar, pod device or vape pen are good choices, as they are discreet, make small clouds and can give high amounts of nicotine. You can use patches with a vape if you need to, as these give ongoing support by releasing nicotine slowly. Some people find vaping helps them because the hand-to-mouth action is like smoking, plus you get similar sensations, like throat hit (the "kick" in the back of your throat when you inhale).
Although e-liquids do not contain tobacco, they contain chemicals, usually including flavorings, and often contain nicotine, which is addictive. Aerosol from e-cigarettes can also include cancer-causing chemicals, and diacetyl, a chemical used in some e-cigarette flavorings, has been linked with serious lung disease. Some people (most commonly youths or young adults) have experienced seizures while using e-cigarettes.
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.
There are hundreds of brands, and they're sometimes marketed as a way to get your nicotine fix without the danger of cigarettes. The Electronic Cigarette Company is one of the original online vape stores in the UK, founded in 2008. We stock a wide range of electronic cigarettes, vape starter kits, and vaping accessories from leading manufacturers such as Elf Bar, Lost Mary, SMOK, Aspire, Vaporesso, VOOPOO, Innokin, Double Drip, ElfLiq and Riot Squad. Many of those who vape were likely to report issues that kept them from being able to safely dispose of their used and empty e-cigarette products. More than half (57.8%) of those who had used e-cigarettes in the past month found it inconvenient to dispose of e-cigarette waste responsibly.
This includes quit coaching, up to 2 weeks of nicotine replacement therapy, and a youth digital program for those ages 13-17. Vuse, owned by Reynolds American, and Juul control about 60% of the market, while hundreds of disposable brands account for the rest. While nicotine is the addictive substance in cigarettes, most of the harm from smoking comes from the thousands of other chemicals in tobacco smoke, many of which are toxic.
E-cigarettes are not risk-free but are believed to cause less harm than smoking. They do not burn tobacco or produce tar or carbon monoxide — two of the most harmful parts of tobacco smoke. Smoking can raise your risk for periodontal disease or disease affecting the gums.
Current evidence indicates that using e-cigarettes is dangerous, especially for young people and people who have never smoked. In young people, the use of nicotine can impact the reward system in the brain. In time, this can make the use of other drugs, such as cocaine, more pleasurable, according to the National Institute on Drug Abuse (NIDA).
Refillable pod mods use replaceable pods that contain either a built-in or removable coil. They are designed to be easier to use than vape pens as they adopt a secure magnetic connection between the pod and battery instead of a tank with a screw mechanism. They have few features and are compact, appealing to those new to the world of vaping and those wanting to upgrade to something simple. The term " vape pen" normally refers to a vape kit consisting of a refillable tank and a rechargeable battery; they are often slim and shaped like a pen, but not always!
The replaceable liquid cartridge contains nicotine mixed with a base (usually propylene glycol), along with flavorings and chemicals. The tip often contains LED lights that simulate the glow of a burning cigarette. Nicotine poisoning can occur when someone ingests, inhales, or absorbs nicotine through the skin or eyes. It can be particularly dangerous for children and young adults, as they are more susceptible to the effects of nicotine. The tax must be broken out as a separate amount from the products sold in any transaction.
Vapes are often viewed and marketed as a safe alternative to smoking. Secondhand smoke can cause heart disease, stroke, and lung cancer in people who don’t smoke. They compared this information against vape and cigarette sales data over four-week intervals from January 2018 through March 2023, a period during which flavor restrictions went from affecting 1.3% of the U.S. population to affecting 38%.
Nationally, more than 8 of every 10 youth, aged years who use e-cigarettes said they use flavored e-cigarettes. More than 9 of every 10 young adult e-cigarette users said they use e-cigarettes flavored to taste like menthol, alcohol, candy, fruit, chocolate, or other sweets. E-cigarettes and vaping devices are not covered by federal law restricting cigarette advertising. Like other e-cigarettes, these are battery-powered device that heats a nicotine liquid to produce an aerosol that is inhaled.
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).
Overall, comparisons of the particle-size distribution in aerosols from e-cigarettes found that the substances tested had particle distributions similar to the traditional e-liquids containing nicotine. "Our finding indicates that health care expenditures for a person who uses e-cigarettes are $2,024 more per year than for a person who doesn’t use any tobacco products," said lead author Yingning Wang, PhD, of the UCSF Institute for Health & Aging. Use of electronic cigarettes costs the United States $15 billion annually in health care expenditures – more than $2,000 per person a year – according to a study by researchers at the UC San Francisco School of Nursing. Between 2016 and 2022–2023, the proportion of people who both smoked regular (combustible) tobacco cigarettes and used e‑cigarettes increased, as did the proportion who currently used e‑cigarettes but did not use regular cigarettes.
In this particular aspect, again the composition of the e-liquid varies significantly among different commercial brands [4, 35]. The most common and major components of e-liquids are PG or 1,2-propanediol, and glycerol or glycerine (propane-1,2,3-triol). Both types of compounds are used as humectants to prevent the e-liquid from drying out [2, 53] and are classified by the Food and Drug Administration (FDA) as "Generally Recognised as Safe" [54].
Many people believe electronic cigarettes (also called e-cigarettes or vapes) are a safe alternative to traditional cigarettes. But with a recent report from the U.S. surgeon general calling e-cigarette use "a major public health concern," this may not be the case. The FDA reports an alarming 900% rise in e-cigarette use among high school students from 2011 to 2015 and the number of high school students using them increased 78% in 2018 alone. Vaping doesn’t create second-hand smoke.Breathing in second-hand smoke is a health risk for people who are around cigarette smokers, including vapers. In addition, third-hand smoke on clothes and furniture is smelly and can be dangerous for people with respiratory conditions. Vaping doesn’t produce the same smelly fumes as cigarettes, but the secondhand vapor contains chemicals and compounds that pollute the indoor air.
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.

E-liquid physical properties are also important in carbonyl formation15,47,84,86. The viscosity and density of the e-liquid determine its mobility, capillary action, and delivery to the wick and coil, influencing the likelihood of a dry puff15. Sub-ohm vapes (sometimes called cloud kits) are more advanced vaping devices that are capable of outputting huge amounts of power; if you’ve ever noticed someone exhaling gigantic clouds from their kit, they were probably using one of these! Using a sub-ohm device requires a working knowledge of battery safety and Ohm’s Law, so it’s best to do some reading before investing in one. "India should be taking lessons from the West where vaping has become an epidemic. Claims that e-cigarettes aid cessation is a big lie, rather they are gateway devices.
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.
Median odds ratio (MOR), which shows the difference between two respondents with identical student-level characteristics from two randomly chosen different schools, was calculated to express between-school variance on the odds ratio scale [36]. The analysis was not pre-registered, and the results should be considered exploratory. Scholastic Real Cost of VapingThe FDA collaborated with the Scholastic Corporation to develop lessons, activities and resources for teachers to increase awareness about the health consequences of youth e-cigarette use. Stanford Medicine is an integrated academic health system comprising the Stanford School of Medicine and adult and pediatric health care delivery systems. Together, they harness the full potential of biomedicine through collaborative research, education and clinical care for patients. This study was the first to use endothelial cells derived from iPS cells to directly investigate the effect of e-liquids with and without nicotine on their viability and function.
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.
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.
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.
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).

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.
When I exhale, the vapor is gone within 10 seconds, along with the smell. Funny how just about 10 years ago people were still allowed to smoke actual cigarettes in some restaurants and I didn’t see anyone walking out on their meal due to the smell coming from the smoking section. I’m not saying it was a wonderful arrangement, but people dealt with it.
Vaping is when you use a small, handheld device (like e-cigarettes, vape pens or mods) to inhale a mist of nicotine and flavoring (e-liquid). It’s similar to smoking a cigarette, but vaping heats tiny particles out of a liquid rather than burning tobacco. On May 15, 2019 a federal judge sided with the American Lung Association and our partners in this lawsuit. The judge concluded that FDA acted unlawfully by delaying requiring e-cigarettes and other newly deemed tobacco products to go through a pre-market review process. The judge subsequently ruled that the filing deadline for all premarket review applications is May 12, 2020.
To truly help tobacco users quit and to strengthen global tobacco control, governments need to scale up policies and interventions that we know work. Tried and tested interventions, such as brief advice from health professionals, national toll-free quit lines and mobile and digital cessation services are recommended. Where economically feasible, governments should also consider promoting nicotine replacement therapies and non-nicotine pharmacotherapies for cessation. E-cigarette emissions typically contain nicotine and other toxic substances that are harmful to both users and non-users who are exposed to the aerosols second-hand.
Even if you’re a tobacco user, having an open, honest discussion with your teen can help. The most important thing to understand is that the liquid in e-cigarette cartridges is not regulated by the FDA. Keep reading to learn more about vaping and how it’s affecting young people.
E-cigarettes and vape products are not FDA-approved cessation devices. For more information and support to help you quit contact the Georgia Tobacco Quit Line. Electronic cigarettes (e-cigarettes) and other vapor products are used to heat and aerosolize (turn into particles) liquid known as e-juice (vape juice) containing highly addictive nicotine or other substances that a person can inhale into their lungs.
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.
Children and adults can develop nicotine poisoning from swallowing, breathing, or absorbing e-liquid through their skin or eyes. E-cigarette use can also result in serious injury due to defective batteries that have caused fires and explosions. Vaping and smoking both involve inhaling nicotine and other substances into the lungs. While cigarettes burn tobacco that produces smoke, e-cigarettes heat liquid to make an aerosol that often contains nicotine, various chemicals, heavy metals (nickel, tin, and lead) and small particles that can be inhaled deeply into the lungs.
The 2019 outbreak of EVALI cases emerged against a backdrop of an ongoing vaping epidemic among youth. The amount, quantity and toxicity of substances that e-cigarettes release depend on several factors, such as the type of device, how the device operates and is used, and the e-liquid used. Drop the Vape also directs users to the New York State Quitline for free and confidential quit-coaching via telephone, internet, and text, and free starter kits of nicotine replacement therapy (NRT) for eligible New Yorkers. In absence of federal law, states are acting to remove flavored nicotine products from the shelves. All the e-cigarettes previously authorized by the FDA have been tobacco, which isn’t widely used by young people who vape.
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.
"Recent studies should make us all more concerned about the impact of traditional and e-cigarettes on the heart as well," Dr. Cireddu says. According to the 2018 NAP report, secondhand vapor contains nicotine, particulate matter, and volatile organic compounds (VOCs) at concentrations that are above recommended levels. The 2018 NAP report found that there’s some evidence that e-cigarette exposure has adverse effects on the respiratory system. Some studies suggest that vaping may have negative effects on the lungs, but more research is needed.
E-cigarettes can help people stop smoking and are an effective stop smoking tool. There’s no safe level of smoking, so it is important to stop tobacco-use completely. You may have heard different things in the media about the side effects of vaping. This page gives an overview of what we know so far about how vaping can affect your health. Our information relates to legal e-cigarettes – ones that are registered with the UK Medicines and Healthcare products Regulatory Authority (MHRA).
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.
Originally, it was thought that vaping might be helpful for people trying to quit smoking. Some e-cigarette labels have claimed that the product had no nicotine when, in fact, it was in the vapor. For this reason, it’s important to use only trusted brands if you vape. E-cigarettes are still relatively new, so their long-term effects are unknown.
They then compiled these rates into one score to determine the 'healthiest' and 'unhealthiest' states for kids. Overall, recent figures from JAMA suggest more than 2million kids under 18 vape regularly, along with 17million adults. Combined with smoking, it may accelerate these effects, leading to osteoporosis. Nicotine causes blood vessels to tighten, which restricts the flow of blood. Smoking also raises blood pressure, weakens blood vessel walls, and increases your risk of blood clots. It can also damage the DNA in sperm, making it difficult to conceive and increasing the risk of miscarriage and certain birth defects.

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.
They usually contain nicotine, which is the addictive chemical in cigarettes. E-cigarettes do not contain tobacco, which is the harmful part of cigarettes that causes cancer. By comparison, traditional cigarette sales have fallen by 5.2% since July 2023, while smokeless and oral nicotine products — led foremost by Zyn products — are up 11.8% as a category. Amid the increasing popularity of e-cigarettes and vapes among young people, health experts from PGIMER have raised concerns. They pointed out that many young people mistakenly think that e-cigarettes are "cool" because of their flavours, sleek designs, and social appeal. Experts warn that this misconception greatly increases the chances of non-smoking youth using regular cigarettes.
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.
In December 2019, the federal government raised the legal minimum age of sale of tobacco products from 18 to 21 years, and in January 2020, the FDA issued a policy on the sale of flavored vaping cartridges. The e-liquid in most e-cigarettes contains nicotine, the same addictive drug that is in regular cigarettes, cigars, hookah, and other tobacco products. However, nicotine levels are not the same in all types of e-cigarettes, and sometimes product labels do not list the true nicotine content. Products marketed for therapeutic purposes (for example, marketed as a product to help people quit smoking) are regulated by FDA’s Center for Drug Evaluation and Research (CDER).
A 2021 review found people who used e-cigarettes to quit smoking, as well as having expert face-to-face support, can be up to twice as likely to succeed as people who used other nicotine replacement products, such as patches or gum. Vaping involves using a device known as an e-cigarette—also called a vape pen, mod, or tank—to heat up a small amount of liquid, turning it into a vapor that can be inhaled. Most vape liquids contain substances such as propylene glycol and glycerol as base ingredients that create the vapor.
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.
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.
The length of time spent vaping can be much longer than smoking a standard cigarette. While most cigarettes are smoked within two to five minutes, e-cigarettes can last up to 20 minutes, delivering more nicotine and damaging chemicals to the lungs. In addition, some vaping mixtures can contain 20 times the nicotine that a single cigarette contains. This study builds on the findings of an earlier randomized clinical trial of This is Quitting conducted among roughly 2,600 young adults ages 18 to 24.
Indeed, one of the limitations of the study was that human cells are not exposed to e-liquids per se, but rather to the aerosols where the concentrations are lower [86]. In this line, the maximum concentration tested (1000 µM) would correspond to approximately 80 to 150 ppm, which is far higher than the levels found in aerosols of some of these compounds [84]. Moreover, on a day-to-day basis, lungs of e-cigarette users are not constantly exposed to these chemicals for 24 h at these concentrations. Similar limitations were found when five of seven flavourings were found to cause cytotoxicity in human bronchial epithelial cells [87]. It is well known that nicotine is extremely addictive and has a multitude of harmful effects. Nicotine has significant biologic activity and adversely affects several physiological systems including the cardiovascular, respiratory, immunological and reproductive systems, and can also compromise lung and kidney function [41].
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.
Once discarded into the environment, the filters create a large waste problem. Synthetic particulate filters may remove some of the tar before it reaches the smoker. The data underlying this article cannot be shared publicly due to the privacy of individuals that participated in the study.
However, more research is needed to fully understand emissions from e-cigarettes and their impact on human health. These aerosols can contain potentially harmful substances — including nicotine, formaldehyde and metals — some of which cause cancer and other harmful health effects. Some e-cigarette brands and other nicotine products state they contain synthetic nicotine rather than nicotine made from or derived from tobacco.
Silica was commonly the first material to be used as a wick, followed by cotton and ceramic3,13,14,15. Cotton has good wicking properties but is less thermally stable than silica14,16,17, while ceramic is chemically stable and heat-resistant18. The use of microporous ceramic as a wicking material has increased in the past few years14,16,18,19,20. Its application has been reported to improve heating efficiency and reduce charring14,16,18,19,20. Additional research is ongoing to clarify the dangers from vaping, and how vaping damages the lungs and other organs. Long-term human studies, in particular, could bring the risks from e-cigarettes into better focus, Crotty Alexander says.
Please be advised that many of these stories contain graphic and upsetting photos of injuries. Exposure to nicotine can also rewire a young brain to become more easily addicted to other substances, including cocaine and alcohol. Even if a cartridge doesn’t contain nicotine, other harmful chemicals may be present.
The Policy Scan Project, by the Institute for Global Tobacco Control (at Johns Hopkins University) tracks and reports regulatory approaches to e-cigarettes around the world. In 2012 and 2013 there was a flurry of tobacco company investment in e-cigarettes, both in the United Kingdom (UK) and in the United States (US), a trend which continued in subsequent years. In 2018, 8% of Pierce County 12th graders said they had smoked a cigarette in the past 30 days. NSW Health acknowledges the people of the many traditional countries and language groups of New South Wales.
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.
This solution typically contains propylene glycol or glycerol, nicotine, and flavouring agents. Indeed, the "vapor" may have a lot more than those five ingredients listed above. Some studies have found it to contain lead, nickel, tin, and silver from the machinery inside the devices along with formaldehyde, manganese, tolulene, and other ingredients linked to cancer, central nervous system problems, and other possible health issues. A 2018 study of e-cig smokers’ urine found at least five of the same carcinogens found in cigarettes.
Of note, the abstinence rate found in the nicotine-replacement group was lower than what is usually expected with this therapy. Nevertheless, the incidence of throat and mouth irritation was higher in the e-cigarette group than in the nicotine-replacement group (65.3% vs. 51.2%, respectively). Also, the participant adherence to the treatment after 1-year abstinence was significantly higher in the e-cigarette group (80%) than in nicotine-replacement products group (9%) [100]. These data overall indicate that the harmful effects of nicotine should not be underestimated. Despite the established regulations, some inaccuracies in nicotine content labelling remain in different brands of e-liquids.
"If there was good evidence that people were using e-cigarettes just to quit smoking, there would be wide support," Benowitz says. "The problem is most of the e-cigarette use in the U.S. is dual use with cigarettes." People use e-cigs in places or situations where they can't smoke, like in a restaurant, but continue lighting up when they can, he explains. "My reading of the evidence is that it is quite convincing that e-cigarettes are helping some people quit smoking." Many young e-cigarette users reported throwing away, improperly recycling, or littering the devices. Only 15% of young e-cigarette users reported disposing of empty pods or disposable vapes by dropping them off or sending them for electronic recycling.
It would seem that future studies should analyse the possible toxic effects of humectants and related products at concentrations similar to those that e-cigarette vapers are exposed to reach conclusive results. Vape aerosols are not just harmless water vapors that are inhaled and exhaled (as marketed). Vape aerosol exposure is unsafe and contains chemicals, metals (i.e., lead, nickel), and other particles that can interfere with lung development and health.
This data brief demonstrates that teens whose environments put them at risk for use of e-cigarettes are more likely to try them. The study, published on May 23, 2022, in Tobacco Control, is the first to look at the health care costs of e-cigarette use among adults 18 and older. The second most supported measure, strengthening restrictions on the advertising and promotion of e‑cigarettes, was supported by 82% of people. In 2019, only 67% of people in Australia supported strengthening these restrictions. The proportion of people neither smoking regular cigarettes nor using e‑cigarettes has remained stable (Figure 3).
Altria Group chief executive William Gifford told analysts during a second-quarter conference call that makers of unregulated e-cigarettes are responding to consumers’ switching to nicotine pouches. According to the latest Nielsen convenience store report released Wednesday, Zyn sales have jumped 74.6% year-over-year with total annual sales now in the $2 billion range. Tobacco industry executives and analysts are sounding alarms about a surge of unregulated nicotine pouches entering the U.S. that is chipping away at regulated products.
