What is MDMA?

3,4-methylenedioxy-methamphetamine (MDMA) is a synthetic drug that alters mood and perception (awareness of surrounding objects and conditions). It is chemically similar to both stimulants and hallucinogens, producing feelings of increased energy, pleasure, emotional warmth, and distorted sensory and time perception. MDMA was initially popular in the nightclub scene and at all-night dance parties (“raves”), but the drug now affects a broader range of people who more commonly call the drug Ecstasy or Molly.

How do people use MDMA?

People who use MDMA usually take it as a capsule or tablet, though some swallow it in liquid form or snort the powder. The popular nickname Molly (slang for “molecular”) 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 (see “Added Risk of MDMA”). Some people take MDMA in combination with other drugs such as alcohol or marijuana.

What are other health effects of MDMA?

High doses of MDMA can affect the body’s ability to regulate temperature. This can lead to a spike in body temperature that can occasionally result in liver, kidney, or heart failure or even death. In addition, because MDMA can promote trust and closeness, its use—especially combined with sildenafil (Viagra®)—may encourage unsafe sexual behavior. This increases people’s risk of contracting or transmitting HIV/AIDS or hepatitis.
