i might drink to get drunk once a month.
for a while, when i was 18/19, i smoked some weed, not much and not often, lasted a couple weeks. met my g/f, it bothered her, and it wasnt something i was anywhere near dependant on, so i gave it up
although, i did go out with her to a buddies about 2 weeks ago and smoked with his g/f (my gf even hit the bowl...??. lol) and i got high as fuck. i doubt if that will hsppen again, and if it does, it will probably be years away
