An illegal substance that is smokeable. There are all kinds of names for this word, which are used all the time referring to it (a LOT of'em are my terms for marijuana):
*Stuff (my term for it; also "The Stuff")
*Blow (also a term for cocaine
*Peacepipe (usually used for native american types)
*Pipe (depends greatly, although unfortunately a lot of pipes contain marijuana)
......and MANY more terms.
"I don't smoke marijuana, especially ever since the first time I got ripped in early May 2002. It fucks with one's mind...I don't need that."
