I enjoy a drew acid cigar or a shisha hooka session very occasionally (maybe 2x/year). For myself, nicotine is a fun buzz for a change up, it really depends on the company and the occasion.
Smoking is bad, but interestingly cannabis smoke is nowhere near as harmful for the lungs. This is because it has a heavier density than tobacco smoke. Elite long-distance runners will puff on a doobie occasionally to increase their lung capacity because the smoke gathers at the bottom of the lungs, and
expands.
Tobacco smoke has the opposite effect because it is lighter in density, and gathers at the top of the lungs congesting the bronchial pathways. And when you get into the toxic additives that big tobacco chooses to include in commercial cigarettes, all bets are off health-wise.
Second-hand smoke is way worse to inhale (carbon monoxide), so I can see the point of all the laws.
I would love it if American Spirit could publish data about how many
occasional organic tobacco users have health issues related to smoking: my guess would be none.
edit: The list of 599 approved additives in cigarettes is something every smoker should see. That's how tobacco, not nicotine, kills. While nicotine is physically addictive, it's not deadly.
