I can think of lots of things I don't want to taste when I kiss someone: hard liquor, beer, garlic, onions, tomato juice, cigarette smoke, fish... I guess I haven't had much experience kissing someone who has just smoked a joint, so I can't comment on the taste.

But I have to ask: if you all wouldn't date someone who smoked a joint, would you also not date someone who drank alcohol?
