I drink maybe 4 drinks total a month. I get where you're going with that though. There is actually data out there on smoking, and having a cigar once in a while isn't really more unsafe than sitting by the camp fire. Your body also recovers itself in most regards rather quickly after chronic smoking (months). I'm not a smoker, and it's better not to smoke because it's super addictive, but having a smoke is like having a drink, not unsafe per say. I'm more worried about sugar than alcohol.
