when you’re in a room- you inhale a lot of the smoke- as it lingers in the air around you- but yeah, it was likely mostly the ciggs that caused it-
This is anecdotal, I know, but I know of one regular (daily) cigar smoker (who had no history of smoking cigarettes) who died of lung cancer. It does happen.
Rush used a room filter system. Very little smoke.
Don't go there..........
