As a toxicologist with expertise in drug detection and metabolism, I can provide you with a detailed answer regarding the detection time of ecstasy, which is the street name for the drug MDMA (3,4-methylenedioxy-N-methylamphetamine), in hair samples.
Firstly, it's important to understand that hair testing is a non-invasive method used to detect drug use over a prolonged period, typically up to 90 days. This is because hair grows at an average rate of about 0.5 inches (1.27 centimeters) per month, and each segment of hair represents a specific time frame of drug exposure.
The detection of MDMA in hair is possible because the drug and its metabolites can be incorporated into the hair shaft as it grows. However, the length of time that ecstasy stays detectable in hair can vary based on several factors, including the dosage taken, the frequency of use, the individual's metabolism, and the sensitivity of the testing method used.
It's worth noting that while amphetamine and MDMA are structurally similar, they are distinct substances with different detection profiles. Amphetamine can be detected in hair for up to 90 days, but this does not necessarily mean the same applies to MDMA. An expanded test that can specifically test for MDMA is more accurate for determining the presence of ecstasy use.
The half-life of MDMA is relatively short, approximately 8 hours, which means that after ingestion, half of the drug is eliminated from the body every 8 hours. However, the detection window in hair is much longer due to the way hair captures and retains substances over time.
For a non-frequent user, the chances of detecting MDMA in hair may decrease significantly after a few weeks, while for a heavy or chronic user, it may be detectable for the full 90-day period. It's also important to consider that hair tests can be influenced by the hair's characteristics, such as its color, texture, and the presence of hair products, which can sometimes affect the results.
In summary, while the detection of ecstasy in hair can potentially last up to 90 days, the actual time frame may vary. It's crucial to approach hair testing with an understanding of its limitations and the factors that can influence the results. An expanded test that specifically targets MDMA is the most reliable method for detecting ecstasy use in hair samples.

Amphetamine will stay in your hair for up to 90 days.. An expanded test CAN test for MDMA (differing from amphetamine) but that's not on the table.. so basically.. 90 days and your safe (although you'd probably be safe alot quicker if your not a heavy user)..Nov 25, 2008
