Methamphetamine
LSD
Marijuana
MDMA (Ecstasy)
LSD or lysergic acid diethylamide. Derived from ergot, a fungus that grows on rye, it originally was marketed under the brand name Delysid and used as a psychiatric therapy aid. Non-medical use of the drug in the 1960s led to it being declared illegal in 1966.
