Marijuana, the most commonly used illegal drug in the U.S., has spawned a huge number of nicknames. Some of these are familiar to many of us from the '60s and '70s (pot, herb, grass, weed, Mary Jane, reefer). Others are more recent: Aunt Mary, skunk, boom, gangster, kif, ganja, Texas tea, Maui wowie, and Chronic are slang for different types of marijuana.
