An obscure, youthful film director known as John Waters filmed a notorious "No Smoking" PSA to be shown in theaters. And show it they did, before Rocky Horror, and before his film festivals, thereby eliciting gales of laughter from the LGBTs, club kids, goths, and straights alike.

In the mid-90s, I attended a live lecture by John Waters at a San Diego university campus, and smoke he did, in a non-smoking building on a tobacco-restricted campus, and he took approximately 2 drags while the thing turned into a long cylinder of ash.

It's been really difficult, and somewhat undesirable, for airlines and other places to eliminate smoking. Especially when there's literally nowhere to take refuge whilst in the air on a long flight.

I've also been incarcerated in mental hospitals where smoking was practically encouraged/required. We would all go "take a break" in an enclosed courtyard, and if you didn't smoke, you definitely got it second-hand, up close and personal.

Although nicotine is generally a stimulant, it's also a laxative and people who can't smoke become extremely anxious and agitated. I suspect that commercial flights today have escalating discipline problems with passengers who become extremely unruly just from hunger or jonesing for nicotine. Flight crews should dole out complimentary transdermals.

So it is generally considered best for psychiatry to allow smokers to smoke, keeping the peace wherever possible. Although the last place in 2023 insisted on providing specially-formulated "House Cigarettes", so psychiatry may also have taken control of cigarette manufacturing to some degree.
