Determining exactly how long ecstasy is detectable in the body depends on many variables, including which kind drug test is being used. Ecstasy - also known as Adam, 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 ecstasy 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 ecstasy will show up on a drug test.

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

How Long Does Ecstasy Show Up in Urine?

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

How Long Does Ecstasy Stay in the Blood?

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

How Long Will Ecstasy Show Up in a Saliva Test?

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

How Long Does Ecstasy Remain in Hair?

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

How Does Ecstasy Build Up in the System?

While the effects of ecstasy usually last about 3-5 hours, the half-life of the drug is closer to 8-9 hours. Therefore, users of ecstasy 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 ecstasy use can diminish after 3-5 hours, the side-effects can last up to 24 hours.

These effects can include enhanced impulsivity and difficulty in maintaining attention during complex tasks.

Research has found that after a single dose (56 mg) ecstasy users can exhibit an acceptance of higher levels of risk, acute changes in cognitive performance, and impaired information processing ability.

For these and other reasons, driving while using ecstasy is considered impaired driving.

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

Effects of Ecstasy (MDMA or Molly)

Some of the effects of using ecstasy can linger for days. 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

Spikes in Body Temperature

Another danger of using ecstasty is it has been found to hamper the body's ability to regulate its temperature. Users therefore can experience extreme spikes in their body temperature that can result in heart, kidney, and liver failure, health officials report.

Most of the deaths attributed to ecstasy use have been blamed on these increases in body temperatures.

Another Ecstasy Factor

Ecstasy is an illegally manufactured drug. You never really know what you are getting. It could contain other drugs and substances that can be detected in a drug test long after the ecstasy is out of the system.

Ecstasy pill purchased on the street can also contain other substances which interact negatively with alcohol, adding another level of danger to their use.
