Weed, because that's what it is and was, long before the fucking gov. chopped/burned them all. Cannabis, because that is its real name. Drugs, just for kicks with friends. Let's go smoke some drugs! Marijuana is a pretty name. Bud, for those times when you're damn serious about tokin' up or buying. "Let's go get some fuckin' bud, man." Those are the names I use.
id liek to start calling it grass, but i suspect youd get many funny looks now-a-days if you asked someone if you could score some grass
Either weed or bud. I hate the sound of the word "pot" when referring to marijuana. It slipped out of my mouth yesterday while I was talking about it and in my head I went "why the hell did I say that?"
