If you have thought about trying to kick a smoking habit, youre not alone. Nearly 7 of 10 smokers say they want to stop. Quitting smoking is one of the best things you can do for your health smoking harms nearly every organ in your body, including your heart. Nearly one-third of deaths from heart disease are the result of smoking and secondhand smoke.
You might be tempted to turn to electronic cigarettes (e-cigarettes, vape pens, and other nondisposable and disposable vaping devices) as a way to ease the transition from traditional cigarettes to not smoking at all. But is smoking e-cigarettes (also called vaping) better for you than using tobacco products? Can e-cigarettes help you to stop smoking once and for all?Michael Blaha, M.D., M.P.H., director of clinical research at theJohns Hopkins Ciccarone Center for the Prevention of Heart Disease, shares health information about vaping.
E-cigarettes heat nicotine (extracted from tobacco), flavorings and other chemicals to create an aerosol that you inhale. Regular tobacco cigarettes contain 7,000 chemicals, many of which are toxic. While we dont know exactly what chemicals are in e-cigarettes, Blaha says Theres almost no doubt that vaping exposes you to fewer toxic chemicals than smoking traditional cigarettes.
However, there has been an outbreak of lung injuries and deaths associated with vaping. In February 2020, the Centers for Disease Control and Prevention (CDC) confirmed 2,807 cases of e-cigarette or vaping use-associated lung injury (EVALI) and 68 deaths attributed to that condition.
These cases appear to predominantly affect people who modify their vaping devices or use black market modified e-liquids. This is especially true for vaping products containing THC, explains Blaha.
The CDC has identified vitamin E acetate as a chemical of concern among people with EVALI. Vitamin E acetate is a thickening agent often used in THC vaping products, and it was found in all lung fluid samples of EVALI patients examined by the CDC.
The CDC recommends that people:
Research from The Johns Hopkins University on vape ingredients published in October 2021 reveals thousands of chemical ingredients in vape products, most of which are not yet identified. Among those the team could identify were several potentially harmful substances, including caffeine, three chemicals never previously found in e-cigarettes, a pesticide and two flavorings linked with possible toxic effects and respiratory irritation.
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. Nicotine is a toxic substance. It raises your blood pressure and spikes your adrenaline, which increases your heart rate and the likelihood of having aheart attack.
Is vaping bad for you? There are many unknowns about vaping, including what chemicals make up the vapor and how they affect physical health over the long term. People need to understand that e-cigarettes are potentially dangerous to your health, says Blaha. Emerging data suggestslinks to chronic lung disease and asthma, as well as associations between dual use of e-cigarettes and smoking withcardiovascular disease. Youre exposing yourself to all kinds of chemicals that we dont yet understand and that are probably not safe.
Both e-cigarettes and regular cigarettes contain nicotine, which research suggests may be as addictive as heroin and cocaine. Whats worse, says Blaha, many e-cigarette users get even more nicotine than they would from a combustible tobacco product: Users can buy extra-strength cartridges, which have a higher concentration of nicotine, or increase the e-cigarettes voltage to get a greater hit of the substance.
Although theyve been promoted as an aid to help you quit smoking, e-cigarettes have not received Food and Drug Administration approval as smoking cessation devices. A recent study found that most people who intended to use e-cigarettes to kick the nicotine habit ended up continuing to use traditional and e-cigarettes.
In light of the EVALI outbreak, the CDC advises people who use e-cigarettes for smoking cessation to weigh the risks and benefits and first consider use of other FDA-approved smoking cessation options.
Among youth, e-cigarettes, especially the disposable kind, are more popular than any traditional tobacco product. 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.
According to Blaha, there are three reasons e-cigarettes may be particularly enticing to young people. First, many teens believe vaping is less harmful than smoking. Second, e-cigarettes have a lower per-use cost than traditional cigarettes. Finally, youths and adults find the lack of smoke appealing. With no smell, e-cigarettes reduce some of the stigma of smoking.
What I find most concerning about the rise of vaping is that people who wouldve never smoked otherwise, especially youth, are taking up the habit, says Blaha. Its one thing if you convert from cigarette smoking to vaping. Its quite another thing to start up nicotine use with vaping. And, getting hooked on nicotine often leads to using traditional tobacco products down the road.
Research from the CDC shows that vaping among youth has declined somewhat since 2020. Kids being stuck at home under their parents supervision during the COVID-19 pandemic could contribute to that trend.
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.
When the coronavirus pandemic first began, Blaha says, data show that e-cigarette sales went down, possibly because people were spending more time at home and avoiding stores and public areas.
But Blaha sees a trend that concerns him: rising rates of daily e-cigarette use among all vape users. The number of people who vaped daily used to be 1 in 5, but now its up quite a bit, which is concerning because it implies more nicotine addiction. Im keeping a close eye on that.
Vaping, smoking and other lung irritants can compound the respiratory problems associated with COVID-19.
