Here's a carton of the stuff circa 1935. It was also said to protect you from hangovers.
Its also forcing you to take deep breaths, can be very social, and keep you more present in the moment wherever you are. I very much enjoyed it before I "quit" years ago at two packs a day. Now its just the very occasional few every few years in social environments while drinking. Definitely has an appeal in a high stress environment. If they made non-cancer cigs I'd be back in a heartbeat.
