If my partner smoked it on occasion (outside the house) then it wouldn't be a deal breaker but if smoking daily to the point that there's no weed in the house, shit i need to buy more .. The whole dependency thing is a turn off for me so i'd have to seriously consider if i'd want to be with someone like that. Also i don't like fingers/hands having yellow/brown stains on them, thats a turn off alone (those hands caressing my body, NO).
