To assess the connection between teenage use of e-cigarettes and later established smoking in those who have previously tried cigarettes, the researchers analyzed data concerning adolescents aged between 12 and 17 years who had reported smoking one or more puffs of a cigarette but not more than 100 cigarettes in the Population Assessment of Tobacco and Health survey. But on top of that, there hasn't been a ton of research done on how damaging they can be to kids with or without nicotine - until now.
"Have the conversation around what is this, sit down and really look at what it does have in it", Hans said. This trending, however, has been proved to turn e-cigs teens vapers into regular cigarettes smokers.
While fewer teens are smoking conventional cigarettes, e-cigarette use - or vaping - is growing increasingly popular.
"Unlike adults, particularly cigarette smokers, who commonly report a desire to quit smoking as a main motivator for e-cigarette use, youth are more likely to cite curiosity as a reason to try e-cigarettes".
The chemicals found in the e-cigarette users' bodies were not itemized on the ingredient list of the vape liquids.
Some of the potentially cancer-causing compounds found in those who used e-cigarettes were acrylonitrile, acrolein, propylene oxide, acrylamide and crotonaldehyde.
"Acrylonitrile is a highly poisonous compound used widely in the manufacture of plastics, adhesives and synthetic rubber", the National Center for Biotechnology Information says on its website.
While those who smoke regular cigarettes had the highest levels, the study said e-cigarettes also pose a significant risk, in part because they are often promoted as being safer despite containing numerous same toxic chemicals. Despite massive gains in cutting cigarette use among young adults over the past few decades, e-cigarette use was the most common tobacco product among USA middle- and high-schoolers between 2014 and 2016, according to the Centers for Disease Control and Prevention. Those chemicals, as well, are associated with a higher cancer risk. But public health groups, the surgeon general's office, and the Centers for Disease Control and Prevention worry about evidence that vaping can get teens addicted to nicotine, and will lead them to smoking cigarettes.
"Electronic cigarettes generate nicotine in the vapor".
Many studies support the theory that kids who vape are more likely to go on to use other tobacco products, but there hasn't been much hard evidence about how directly risky e-cigarettes are.
