- with cannabis being illegal, survey data in lung disease patients is contaminated by a desire to hide illegal activity.
This brings up an interesting point that I have mentioned before, but bears repeating: The survey statistics on the number of tobacco smokers are WAY understated, not because tobacco is illegal, but because it is now socially dismissed by many as "low rent".
Therefore, when someone calls from Gallup, and asks "Do you smoke cigarettes?", many people feel compelled to say "No" for social reasons.
Being in the hotel business, I have a unique vantage point from which to view human behavior. Our facility is 100% non-smoking, (not by law, but by our choice) which forces the smokers out into the open (lest they be fined $200 for smoking in the rooms), where it's possible to observe their behavior.
It is my observation that the number of adult smokers is closer to 40%, rather than the 18% figure that is oft-reported.
IMHO, this figure is probably warped toward the high end by what I call "vacation smokers". These are the people who come to the island to completely blow off steam and let their hair down. After a day or two of partying on the beach, or in one of the many island bars, these folks "smoke socially", just for fun.
When they go back to their real lives, I suspect most of them stop smoking again.
Personally, I would join them in a heartbeat, except I know how hard it was to quit. I was terribly addicted, and fear that a "social smoke" would lead right back to addiction. It's why I haven't tried vaping, even though it looks pretty fun.
That's one thing everyone forgets: Smoking is fun. I LOVED smoking. If they made a cigarette that didn't kill me, I'd smoke again in a heartbeat.
Anyway, if you subtract the "vacation smokers" I think the actual adult smoking rate is still 25 - 30%.
