jooch (n) - Slang term for the JWH research chemicals, most commonly JWH-018. Jooch can refer either to the pure powdered substance, or a legal bud or spice product containing it. Jooch, being a synthetic cannabinoid, produces effects similar to marijuana when smoked or vaporized. Jooch is legal in most jurisdictions and much cheaper than the real thing.
I smoked all my jooch last night and heard a rainbow.
