How Long Does Ecstasy Stay In Your System?

How long does MDMA (ecstasy, molly) stay in your system?

The acute effects of MDMA, the main component of ecstasy, often last around three to six hours for most adults. Its half-life, that is the amount of time it takes for half of the drug to be processed by the body, is around eight to nine hours.[1]

While the drug leaves the body's system quickly, traces of MDMA can be detected for up to 90 days after the last dose.
