Detection times need to be considered in conjunction with the weight, age, gender and general health of the user. The following figures are intended as a rough guide to the elimination times of ecstasy from the body. Ecstasy is detectable in hair samples for 6 months after use and longer, although the accuracy of the tests declines with time. It is measurable in urine for up to 72 hours and in saliva for up to 48 hours. The presence and quantity of ecstasy can be detected in blood for up to 24 hours after use.
