I went and looked for myself and it appears the jury is still out on the risks of Zyn, etc

Stepping outside for a smoke on the job, at parties, while out running errands, in foreign countries as a tourist, to kill time outside an appointment waiting room, etc. was a guaranteed way to strike up an unexpected conversation with all manners of characters from all walks and levels of life that I wouldn't have had the chance (or courage or social skills I suppose) to do otherwise.

Some of the most entertaining or thought provoking conversations with strangers in my life have been a result of this. Approaching random people busy with their random lives outside of a smoking area feels intimidating and often doesn't seem to have the same result (which makes sense- someone smoking is actively not busy)

And in the office, it always felt to me like the smoking areas were the only place you could get real, no bullshit answers from people across teams/divisions "off the record" about actual deadlines/timelines etc.

I've heard people say something to the effect of, just go hang out in a smoke spot and don't actually smoke to get the same perks but as an ex-smoker if I saw a non-smoker doing this I would definitely feel a bit weird about it / less open towards them.
