Cannabis: Weed, dope, blow, kush, MJ, mary, jane, mary-jane, cannabis, green, and good.

I call benadryl benny or ben, and a combination of cannabis and benadryl "Ben and Mary" or "Ben and Jane". Too bad I've never actually done the two simultaneously before, but I plan to in the future.

LSD: Acid, cid, LSD. (I've never done this either)


EDIT: To the post above, every once in a great while, I'll call it "Mara-juh-wanna". I rarely ever do it though, only when in a joking mood.
