This is the thing that's so tricky about... well, I guess the way our world models in general work.
Is drinking bad for you? Yup. Is smoking bad for you? Yup.
Is moderate social drinking bad for you? Likely, but definitely less bad for you than slamming a 6-pack nightly.
Are there other (mainly socially-mediated) health benefits from moderate social drinking? Plausibly? Probably? Occasional social smoking? Probably in some contexts.
If these effects both exist, they can be compared. Do the risk curves intersect? Where? The crossover will land in different places for different people, different circumstances.
