By now, you’ve probably seen people puffing on all sorts of odd-looking devices, walked through clouds of vapor on the street, and maybe even tried an e-cigarette yourself. It’s pretty safe to say—e-cigs are officially a thing.
So what are e-cigarettes anyway, and what do we know—and not know—about the risks?
First, let’s clear up a quick misconception: College students may not be using e-cigs as often as you think. In a 2016 nationwide survey, students thought that only 16 percent of their peers had never tried an e-cig. The reality? Eighty-five percent of students say they’ve never puffed on one (American College Health Association, National College Health Assessment, Fall 2016).
But even if our perception of how many students are smoking e-cigs is off, that doesn’t mean they’re not a problem. According to the 2013–2014 National Adult Tobacco Survey, 14 percent of young adults (ages 18–24) are using e-cigarettes as are 6 percent of those 25 and older.
E-cigarettes, vaporizers, and ENDS
There’s a lot of lingo associated with e-cigarettes and vaping, and trying to follow it can get a little confusing.
- Any device that lets you inhale an aerosol of chemicals (usually including nicotine) is considered an e-cigarette, according to the FDA.
- Some e-cigarettes look like regular cigarettes. Others, called vaporizers, don’t. Yup, file this under the confusing part. There are also e-hookahs, e-cigars, and e-pens. All of these are known as electronic nicotine delivery systems (ENDS).
- Vaporizers and e-cigarettes have a tank that holds liquid chemicals. There’s a heating element—usually a battery—that turns the liquid into an aerosol that is then inhaled.
- The liquid is called e-liquid or e-juice. The e-liquid in e-cigarettes and vaporizers often (though not always) contains nicotine (in varying amounts), flavors, and other chemicals.
What do experts say about vaping?
Vaping is widely thought to be safer than smoking, but that doesn’t mean it’s risk-free, says Dr. Hayden McRobbie, professor and researcher in the Tobacco Dependence Research Unit at the Wolfson Institute of Preventive Medicine at Queen Mary University of London. Many e-cig products contain nicotine, which is highly addictive and has been shown to harm the developing brain of young adults, according to the surgeon general. The US Food and Drug Administration (FDA) has also found a number of cancer-causing chemicals in vaping products.
E-cigarettes have been available in the United States for about a decade, but not enough studies have been done to know for sure what the long-term risks might be. There are other variables at play, too.
“There are many models of e-cigarettes and vaporizers, including homemade products,” says Dr. Jean-Francois Etter, professor of public health at the Faculty of Medicine of the University of Geneva in Switzerland and an expert in tobacco dependence. Little-known fact #1: There are more than 460 different e-cigs on the market today. Little-known fact #2: They’re so varied—from the number of puffs to the types of liquids to the depth of inhalation—that it’s difficult to assess their risk, Dr. Etter says.
We don’t know yet how e-cigs can affect our health in the long run, but we do know some interesting facts about them.
5 lesser-known facts about vaping and e-cigs
1. Everything is made of chemicals. E-cigarettes have some funky ones.
The FDA started regulating e-cigarettes in 2016, but the agency has not yet evaluated all the chemicals in these products to determine how safe they are. What does that mean for you vapers out there? You have no idea what you’re smoking and neither do we. Many vaping products contain nicotine, which we know is addictive and harmful, and also affects attention and memory in developing brains, according to the American Lung Association. Other ingredients often found in vaping products include propylene glycol, a chemical that helps make smoke, and glycerin, a byproduct created when soap is made. Interestingly enough, glycerin can be found in materials ranging from toothpaste to brake fluid—you probably don’t want to be inhaling either of those.
2. Vaporizer batteries can explode.
Around here, we don’t love exploding electronics, and we bet you don’t either. (Anyone remember the Samsung Note 7 debacle?) While vape battery explosions appear to be rare (only about 25 were reported in the media in a five-year span, according to the US Fire Administration), they can obviously be dangerous and probably pretty terrifying. If you use battery-powered vaping products, here’s how to reduce your battery explosion risk:
- No charger swapping. Only use the charger your vape came with.
- Daytime charging only. Don’t charge your vape at night while you’re sleeping.
- Drop your vape into your reusable water bottle? Replace the batteries anytime they get wet.
- Don’t let the batteries come into contact with anything metal.
- Look for e-cigarettes with safety features, like an automatic shutoff feature when the battery is fully charged.
3. Vaping may increase the likelihood of using traditional tobacco products later on.
Early research suggests that using e-cigs may increase the chances of young people moving on to cigarettes and other traditional tobacco products later on, according to the National Institute on Drug Abuse. An analysis of more than 17,000 14- to 30-year-olds found that those who had ever tried vaping were 3.6 times more likely to start smoking traditional cigarettes than those who had never tried it, while those who had vaped in the past 30 days were more than 4 times more likely than non-vapers to turn to cigarettes (JAMA Pediatrics, 2017). As we know from decades of research, using traditional tobacco products can lead to a host of not-so-fun health issues, such as cancer, heart disease, erectile dysfunction, and emphysema.
4. Dripping can boost your exposure to toxic chemicals.
What’s dripping, you ask? It’s a process of directly inhaling heated e-cig liquid at a higher temperature in order to produce a more concentrated vapor. Preliminary research suggests that doing this may increase the user’s exposure to toxic chemicals such as formaldehyde (a known carcinogen used in glues and adhesives), acetaldehyde (a chemical found in cigarettes and in some foods), and acetone (the active ingredient in nail polish remover) (Pediatrics, 2017). A tip for vapers and probably the rest of us: Avoid dripping.
5. Big tobacco is now playing the vaping game.
The popularity of vaping hasn’t gone unnoticed by big tobacco companies. Tobacco conglomerates started buying up popular e-cigarette companies back in 2012, and they’ve also started making their own e-cig products, according to a 2016 Newsweek special edition. Philip Morris recently filed an application to market a kind of cigarette that heats, rather than burns, tobacco and hopes to advertise it as “less harmful than traditional cigarettes,” according to Reuters.
Look out for anything tobacco companies tout as safe: In the 1920s–1950s, tobacco companies used ads featuring doctors, babies, and even Santa Claus himself to encourage smoking. The tobacco industry is also known for manipulating data and funding research that supports their best interests (read: making money), according to a 2017 editorial published in Public Health Ethics.
The risk of e-cigarettes: TBD
The dangers of traditional tobacco products are many and known; the dangers of e-cigarettes are still being determined. That leaves plenty of unknowns for students mulling whether to vape or not.
“I think that any substance you’re inhaling into your lungs isn’t healthy and should be avoided, at least until more research is done.”
—Jessica W., first-year graduate student, University of New Brunswick, Canada
“It seems to be a healthier option than smoking traditional cigarettes, at least for those who have that addiction. I absolutely think more research should be done on it, though.”
—Katherine B., second-year graduate student, University of Kansas
“It’s a risky habit to start, considering that we don’t know the long-term effects. On the other hand, if the person is a smoker, vaping could be a better option since the negative effects of tobacco are already well known and may outweigh the potential negative effects of vaping.”
—Gillian T., second-year graduate student, Queen’s University, Ontario, Canada
Research published in BMC Medicine in 2015 found that e-cigarettes appear to be less harmful than traditional cigarettes. The researchers also noted that smokers who switched to vaping saw improvements in their respiratory health. “Better than,” though, isn’t the same as “safe,” and it will likely be decades before the risks of e-cigarettes are fully understood.
What about for people trying to quit traditional tobacco?
For people looking to cut down their cigarette habit, vaping may be a useful tool—though the results of recent studies are mixed. Let’s take a closer look: A study including more than 2,000 smokers found that those who also used e-cigarettes were more likely to cut their cigarette use in half than were those who only smoked traditional cigarettes (Addiction, 2017). However, the Centers for Disease Control and Prevention recommend a combination of counseling and nicotine replacement medication (such as the nicotine patch) as the most effective method for quitting smoking.
