Methamphetamine (also called meth, crystal, chalk, and ice, among other terms) is an extremely addictive stimulant drug that is chemically similar to amphetamine. It takes the form of a white, odorless, bitter-tasting crystalline powder.
MDMA (3,4-methylenedioxy-methamphetamine), popularly known as ecstasy or, more recently, as Molly, is a synthetic, psychoactive drug that has similarities to both the stimulant amphetamine and the hallucinogen mescaline. It produces feelings of increased energy, euphoria, emotional warmth and empathy toward others, and distortions in sensory and time perception.
MDMA was initially popular among White adolescents and young adults in the nightclub scene or at “raves” (long dance parties), but the drug now affects a broader range of users and ethnicities.
