Should I quit a friendship with a person who smokes weed?

I have a friend who smoke weed art night and he sleeps during day. When he is high he goes to twitter and babbling with people. I have had a friend who smoke weed heavily. He complain too much about society. Should I stop going out with people who smoke weed? I don’t see the normal relationship with those people at all.
