Ecstasy, molly, and MDMA are commonly known as party drugs as they cause intense feelings of euphoria as well as mild hallucinogenic effects. MDMA has a relatively short half-life but can be detected in toxicology tests long after use.

How long does MDMA stay in your system?

MDMA (3,4-methylenedioxymethamphetamine) falls under multiple drug classifications as it acts as a stimulant, mild hallucinogen, and psychoactive entactogen (a drug component that improves emotional communication and openness).[1]

It is commonly used as a party or club drug as it is reported to improve experiences with other people, increase a sense of “togetherness” and for its mild hallucinogenic effects. 

The acute effects of MDMA 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]

MDMA is not tested on a five-panel drug test (the urine test commonly used by employers for random drug tests) but can show up in some results. The standard five drugs detected in this urine test are:

  • Amphetamines (e.g. meth)

  • Cocaine Metabolites 

  • Marijuana Metabolites (THC)

  • Opiates (e.g. heroin and painkillers)

  • Phencyclidine (PCP)

Factors that affect MDMA detection times

There are many factors that can influence the detection rate in a toxicology test and these can vary from person to person. 

Factors that influence MDMA detection rates include:

  • Length of time MDMA was abused
  • Quantity taken
  • Purity of the drug
  • Whether other substances were taken (such as alcohol or stimulants) 
  • Body mass index (obese people will take longer to process MDMA)
  • Gender
  • Age 
  • Pre-existing medical conditions (especially those involving the liver or kidneys)

Can you get a false-positive MDMA test result?

Many drug tests do not actively search for MDMA metabolites, though the constituent parts of the drug do show up on some tests. 

As MDMA is formed of multiple substances, some other drugs can cause a false-positive result if they contain similar components. For example, a study from 2010 found that trazodone, a prescription antidepressant medication, could cause a false-positive to occur on an ecstasy EMIT II assay test.[2]
