2. Juuling is not a safe alternative to smoking.
Juuling—the term many teens use to describe vaping—is less harmful, in some ways, than cigarette smoking, but it’s still harmful to overall health. Most vape juice contains high levels of nicotine, a highly addictive drug that stimulates the nervous system and can cause long-term medical problems, include heart disease, blood clots, and stomach ulcers. Nicotine can also negatively affect brain development. Vaping also dramatically increases an individual’s chances of becoming a smoker. Teens who vape are almost four times as likely as their peers to begin smoking cigarettes, according to a study published in JAMA Pediatrics.
