Why do guys who smoke marijuana and drink like to date girls who smoke marijuana and drink?

Because they need a common activity.

AnswerBecause most people who don't smoke wouldn't want to kiss someone who does smoke. same with those who don't like the taste of alcohol, a non drinker/smoker wouldn't want to be with someone who does drink/smoke so the person who does those activities has to find someone who does them too since they don't mind the taste or smell of the other person. also people who smoke weed or drink are more chill about life while others arent, so their morals and interests are the same, which equals more compatibility between the two.

Answer

Because a couple would rather sit around smoking a blunt then doing something with a non-smoker.
