How long does ecstasy stay in your system?

MDMA or Ecstasy is usually detectable in urine for 24-72 hours after use. Less than 1% of MDMA remains after 48 hours. MDMA usually is metabolized within 48 hours and therefore the urine would be clean 24 hours after. This amount will not be detectable in blood or urine samples. However, Ecstasy users may test positive for amphetamines in the standard drug test. MDMA is not tested specifically for in the standard urine drug tests. However MDMA users do test positive for amphetamines (the two drugs are chemically similar). Also, many tablets of street ecstasy are not pure MDMA and frequently include ecstasy tablets may contain other substances in addition to MDMA, such as ephedrine (a stimulant); dextromethorphan (DXM, a cough suppressant that has PCP-like effects at high doses); ketamine (an anesthetic also has PCP-like effects); coffeine; cocaine; and methamphetamine, which will show up in a test.
