Ecstasy is an illegal drug that contains the active ingredient MDMA (3,4-methylenedioxymethamphetamine). It’s related to stimulants and hallucinogens and produces both types of effects, making it a popular party drug. Ecstasy sometimes is called Molly.1
The drug comes in a wide variety of sizes, shapes, and colors, so it can be helpful to know what the most common forms of Ecstasy look like—particularly if someone offers you a pill or if you’re a parent or caregiver of a child or teenager who may be exposed to the drug.
