MDMA (an abbreviation of 3,4-methylenedioxymethamphetamine), also called “Molly” or “Ecstasy,” is a lab-made (synthetic) drug that has effects similar to stimulants like methamphetamine. It is typically sold illicitly as colorful tablets with imprinted logos, capsules, powder, or liquid. Some researchers and organizations consider MDMA to be a psychedelic drug because it can also mildly alter visual and time perception. MDMA’s effects may include feeling more energetic and alert and having an increased sense of well-being, warmth, and openness toward others.

MDMA first became popular in nightclubs, but people now take it in a wide range of settings. Researchers are also studying MDMA as a treatment for depression and post-traumatic stress disorder (PTSD) in supervised clinical research trials.

A person may experience the effects of MDMA within 45 minutes or so after taking a single dose. Effects include feeling happy, energetic, alert, and closer to others.^1,2  In addition, people report increased sensitivity to sights, sounds, touch, and smells. These effects peak within 15 to 30 minutes and last an average of three hours.³ However, there may be side effects of using MDMA, some of them potentially dangerous.
