Detection Timetable Depends on Many Variables

Determining exactly how long MDMA is detectable in the body depends on many variables, including which kind drug test is being used. MDMA - also known as Adam, Ecstasy, STP, XTC - can be detected for a shorter time with some tests, but can be "visible" for up to three months in other tests.

The timetable for detecting MDMA in the system is also dependent upon each individual's metabolism, body mass, age, hydration level, physical activity, health conditions and other factors, making it almost impossible to determine an exact time MDMA will show up on a drug test.

The following is an estimated range of times, or detection windows, during which MDMA can be detected by various testing methods:

How Long Does MDMA Show Up in Urine?

MDMA is detectable in a urine test for 2-5 days.

How Long Does MDMA Stay in the Blood?

A blood test will detect MDMA for up to 24 hours.

How Long Will MDMA Show Up in a Saliva Test?

A saliva test will detect MDMA from 1-5 days.

How Long Does MDMA Remain in Hair?

MDMA, like many other drugs, can be detected with a hair follicle drug test for up to 90 days.

How Does MDMA Build Up in the System?

The effects of MDMA usually last about 3-5 hours, but the half-life of the drug is closer to 8-9 hours. Therefore, users of MDMA may try to take more of the drug as the "high" begins to wear off while the first dose is still in their system.

Although the "high" of MDMA use can diminish after 3-5 hours, the side-effects can last up to 24 hours including enhanced impulsivity and difficulty in maintaining attention during complex tasks.

Effects of MDMA (Ecstasy or Molly)

Some of the effects of using MDMA can last even longer. Some users have reported the following side-effects for up to a week after using the drug:

  • Irritability
  • Impulsiveness and aggression
  • Depression
  • Sleep problems
  • Anxiety
  • Memory and attention problems
  • Decreased appetite
  • Decreased interest in and pleasure from sex

    According to the National Institute on Drug Abuse, some of the above effects might be the result of using MDMA with other drugs.

    With only a single dose (56 mg) MDMA users have been found to exhibit an acceptance of higher levels of risk, acute changes in cognitive performance, and impaired information processing ability. Therefore, driving while using MDMA is considered impaired driving.

    Many states have passed zero tolerance laws regarding drugged driving. In those states, if you are found to have any MDMA at all in your system, you could be charged with impaired driving.
