MDMA (3,4-methylenedioxy-methamphetamine) is a synthetic drug that alters mood and perception, producing feelings of increased energy, pleasure, emotional warmth, and distorted sensory and time perception. It is chemically similar to both stimulants and hallucinogens. MDMA is commonly known as ecstasy, although the latter term has now been generalized to cover a wide range of other substances. It acts as both a stimulant and psychedelic, producing an energizing effect, distortions in time and perception, and enhanced enjoyment from sensory experiences. MDMA is usually taken as a capsule or tablet, though some people swallow it in liquid form or snort the powder. The popular nickname Molly often refers to the supposedly "pure" crystalline powder form of MDMA, usually sold in capsules. However, people who purchase powder or capsules sold as Molly often actually get other drugs such as synthetic cathinones ("bath salts") instead. MDMA is a Schedule I drug under the Controlled Substances Act, meaning it has a high potential for abuse and no currently accepted medical use in treatment in the United States.
