Is he a pothead??(I hate the 20 character thing)?!

My friend told me that at a party this guy I like(who may like me back:)) smoked weed,pot and crack the entire party! I asked her if tht was the party where she was high at and she said "yeah y?" i pointed it out to her tht she could've imagined it bc everyone else I ask said he didn't even touch the hostess' weed pack or whatever u call it. I knew she was probably lying bc she doesn't like him. In fact she hates him. But when I went onto his facebook profile he had under Likes, Marijuana and Make Weed Legal. So I started thinking, is it true? I mean, I wouldn't stop liking him just bc he smokes bc i would feel sorry for him that he does tht, tht i'd like him more. Anyway, the thing is, is he jokes around alot on his profile and in real life. So could someone tell me is he really a pothead?

PS: His physical features are: Non bloodshot eyes, perfect white teeth, and smells like not smoke:)
