Out of a sudden I'm curious to see what OCs smoke and/or drink.
michiko and gesaku smoke cigarettes. michiko drank once and got drunk and never tried drinking again. she is a heavier smoker than ayami and gesaku combined - she smokes like 3-4 cigarettes per day. ayami vapes.
michiko smokes weed, too.
"Angel" feeds on pleasure, so he smokes a special cigarette provided by Asmodeus that fills him up with the happy chemicals so he stays fed during work.
