I don't know either, but I haven't heard of e-cig users keeling over right and left due to vaping.... and it's been about ten years, so I'm going to go with a tentative, "probably," but I'm not sure I care that much at this point. We are supposed to live in a free society, so is drinking bad for you? Should we arrest people for being drunk in public? (Tentative no, there, unless they are also doing something else illegal.) Should we arrest people for driving drunk? Even though I was no fan of MADD in my day, YES we should arrest people for driving drunk. And, we shoudn't make "no drinking" a condition of probation either, or even no driving, necessarily, and certainly an interlock after that for a long time.... But look, companies like uber are coming in so cheaply, that drunk driving seems to have lessened, at least in my town. If we were to consult the taxi industry they would demonize ubers and refer to the sensationalized cases of uber drivers getting robbed, etc., they wouldn't be investigating "how does a really inexpensive and easily accessible business model reduce drunk driving...." That would not be their focus.
Since I vape less than 4 ml a day, I certainly don't think I'm ingesting 1 ml of flavorings per day, especially since I dilute my juice with unflavored..... So ah, I can't really say that I think much about that. Also, I'm sensitive and allergic to some things, so I can usually tell if a particular flavor is giving me bad juju.... I'd imagine that if I continued to smoke *that* flavor, I'd have a negative lung outcome. Also, a lot of people concerned about Temp Data are switching to TC, so far seems that issues concerning vaping that arise become a self-correcting problem. It seems (to me) that e-cigs have always wanted to be a harm reduction option, and have consistently self-corrected over time. That is NOT the case with cigarettes, at least at this point. Cigarette makers are not banding together to remove harmful additives, they don't HAVE to, as long as they can keep people addicted. That said, everyone has an agenda, even me, even you. So, I think I'm going to stick on DeAnna's side and say read all you want, but do what's best *for you.* I prefer not to smoke, and if I get lung cancer after 20 years vaping, I'll be happy.... That's 20 years that wasn't in front of me when I was facing COPD at 43, so, ah, I'll take the nominal risk. Period. You don't have to.
