A lot of drugs are unpleasant to administer. It's difficult to think of something more unpleasant than injecting yourself with impure narcotics. Weed smells and tastes awful; stoners end up liking the scent only because it's associated with the experience. Also, I think it's pretty easy to make all of those taste good, with the exception of tobacco (and menthol cigarettes take the worst of the bite out of that, too). Sweetened coffee, flavored dip, sweet mixers to go along with vodka, etc.
