In addition to whatever enjoyment vaping brings, some evidence suggests vaping helps some people stop smoking (though other evidence suggests otherwise). However, there appears to be ample evidence that vaping is not "95% less harmful than smoking" as some have claimed. How vaping affects our overall health is uncertain. Vaping during pregnancy could harm a developing fetus.Accidental exposure to liquid from e-cigarettes has caused acute nicotine poisoning in children and adults.Explosions and burns have been reported with e-cigarettes while recharging the devices, due to defective batteries.Teens who vape are more likely to begin smoking cigarettes.Some substances found in e-cigarette vapor have been linked to an increased risk of cancer.Even some "nicotine-free" e-cigarettes have been found to contain nicotine. Nicotine is highly addictive and can affect the developing brain, potentially harming teens and young adults.A number of other health effects are also worrisome: The tragic and alarming cases of severe lung disease are clearly cause for concern. For example, are lung problems more common among vapers who already have breathing problems (such as asthma) or who smoke other substances, such as regular cigarettes or marijuana? Is it more common among younger individuals? Other health risks of vaping It’s not entirely clear how often vaping might lead to lung trouble or who is at highest risk. What we don’t know about vaping and severe lung disease ![]() The number of new EVALI cases have declined dramatically since September 2019, probably due to public health messaging about a link between THC in e-cigarettes and EVALI and removal of vitamin E acetate from e-cigarettes.Other contaminants and other factors (such as pre-existing lung disease) may also play a role. Experts now suspect contamination with a form of vitamin E (called vitamin E acetate) in some tetrahydrocannabinol (THC)-containing e-cigarettes as the cause of EVALI.Typically, symptoms have started gradually, with shortness of breath and/or chest pain before more severe breathing difficulty led to hospital admission.Most cases were among teens and young adults. More than 2800 e-cigarette users have required hospital admission due to EVALI through February 2020 68 of these people died.This condition is called e-cigarette, or vaping, product use-associated lung injury, or EVALI. You may have seen news reports of sudden and severe lung problems, including deaths, linked to vaping. And while that fact is prominently displayed in advertising, we know from experience with regular cigarettes that warnings don’t always work! Reports link vaping to severe lung disease These devices heat up various flavorings, nicotine, marijuana, or other potentially harmful substances. And more than nine million adults 18 or older use e-cigarettes, according to a 2020 survey by the CDC.Į-cigarettes use a battery-powered device that heats a liquid to form vapors - or, more accurately, aerosol - that the user can inhale (thus "vaping"). Certainly, age restrictions - it’s illegal to sell e-cigarettes to anyone under 21 (18 or 19 in some states) - aren’t preventing use among teens and young adults. A more recent survey found that among high school seniors, more than 40% had tried e-cigarettes. ![]() An estimated 2.1 million middle school and high school students reported using e-cigarettes in 2017 that number jumped to 3.6 million in 2018. According to a 2019 study, about 37% of high school seniors reported vaping in 2018, up from 28% the year before. The rising popularity of vaping has been dramatic, especially among teenagers. ![]()
