Thanks for the translation, Eyedunno!
I'm not sure how much this study correlates with us vaporers who like a little nicotine in our juice. They don't allow it in Japan, although some of the samples did have it. At the very least, as the the last paragraph states, participant's cigarette consumption decreased significantly during the term of the study. I liked the part that says perhaps the decrease could be attributed to the fact the participants were required to do 150 puffs/day and probably just didn't have time to smoke an analog!![]()
Rothenbj says the hand to mouth habit has been broken. However, I have it from a pretty good source that his shoes didn't match and one of them was even on the wrong foot. It's possible that that PARTICULAR night of poker wasn't a fair example of how things are going each and every day. We can only hope.
Oh, and another +1 to Eyedunno!
They need to bring back cigar-smoking at poker tournaments. It draws olfactory attention away from the pungencies wafting from under the table.
Cigars (good ones, at least) actually smell good. as nice as vaping is, nothing replaces those Honey flavored Backwoods! I'm sure they don't have all the nasty crap cigarettes have, either. still bad for you but so good.
From what I've read, most cigars actually produce much more "hazardous" smoke (higher levels of nicotine, carbon monoxide, and particulates are left unfiltered), but since most cigar smokers don't inhale as deeply or as often as cigarette smokers.
Because cigars are generally not inhaled into the deep lung tissue and used far less frequently than cigarette smokers who light up 20+ times a day, most studies fail to find any significant increase in morbidity for cigar or pipe smokers. That is why, along with e-cigarettes and smokeless tobacco, they remain unregulated tobacco products in the US because there is insufficient data to justify most regulations applied to cigarettes.
As a chemist I can tell you that acrolein does NOT form when PG is used. It's formed only when glycerin (or its derivatives, like oils) is heated.
So you mean it comes from the VG instead?
