18 and 19 year olds are in commas, dead right now, or will be soon. This is killing people far faster than cigarettes. I'm of the opinion the small fraction of people claiming they only smoked nicotine are probably lying for reasons mentioned before. They are young kids who don't want to disappoint their families with the fact that they are now dying at a very young age from what used to be a mostly harmless activity (marijuana smoking). There are also settlements and insurance including life insurance, AD & D to consider as well.
Juul Lab's and all the vaping shops need to be put out of business for claiming this is a harmless way of smoking. Kids took that and ran with it as they vaporize God knows what to get high in a stealthy and supposedly, more healthy way.
And this is a more or less useless comparison. Juul has only existed at all for about 4 years. Smoking kills huge numbers of people, but not in 4 years.
AFAIK, the data is consistent with vaping being more dangerous than smoking.
For what it’s worth, humans evolved in the presence of fire. Plant smoke, while quite dangerous, is something that mammal lungs have dealt with, in moderation, forever. Whatever chemical soup is present in vaping vapor is new. And saying “it’s just glycerol” makes no sense. Glycerol has very small vapor pressure at body temperature and boils well above the boiling point of water. Some websites suggest that the actual output from vaping is quite nasty indeed.
Vaping is new.
Maybe these are the early incidents of a yet-to-be-discovered chronic condition that takes a decade plus of vaping to develop.
Hey, millions of high schoolers smoke cigarettes and none of them have lung cancer! (yet)
