We were not MADE to breathe air, actually, Mr. Al Gore. There is this "imaginary" idea that like, non polluted air is what we were "made" for but guess what? There have been volcanoes since the beginning of time, there have been lightning fires, if anyone thinks the golden age of coal was all healthy it WASN'T.
Native Americans have been using non adulterated tobacco at reasonable percentages with little ah, myth of tobacco addiction and COPD, there is a certain AMOUNT of pollution we have EVOLVED to handle and anyone who says anything different is not being realistic. All bets are NOT off any time we don't breath "air" and it is actually AMAZING how long some folks can go smoking cigarettes with few ill effects. It's one of the reasons smoking cigarettes, well, quitting is HARD.
The time you should quit is like 20 years before you HAVE to but really, a lot of the time I was like, "Yeah, I know this stuff is killing me" but it's hard to be that future focused, you have time until you don't. Etc.
I will say heavy duty smoking of the tobacco of today is definitely like, not good. I will also say that I have visited LA on a few occasions and while the air is VILE and ugly, people LIVE there, also smoke, and also keel over dead (eventually) but no, we don't all need oxygen tanks. Or even tanks of "pure mountain air."
I will say 0 NIC vape is probably much better than 3 ppd of Marlboros, so eh.
I don't want to hear it either. Despite everything mortality rates continue to decline. Maybe one day there will be an abrupt reversal of fortune but our lungs were actually and absolutely DESIGNED to filter out a certain number of toxicants.
Please don't go to med school. Although I agree this guy may not need to vape, but if he wants to vape, that is his choice.
We are NOT designed to wear masks 24-7 but that is a WHOLE other debate.
