Quick answer
MDMA (ecstasy/molly) is typically detectable in urine for 1–3 days after any use. It is screened on standard 10-panel, 12-panel drug tests.
Screened on: 10-panel 12-panel
Typical cutoff: Urine: 500 ng/mL initial (when included); 250 ng/mL confirm (MDMA or MDA).
Detection window by test type
| urine | |
|---|---|
| Any use | 1–3 days |
| saliva | |
| Any use | 1–2 days |
| hair | |
| Any use | up to 90 days |
| blood | |
| Any use | ~12–24 hours |
Ranges reflect typical published detection windows and vary with dose, frequency, body composition, hydration and the assay used.
Key details
Classic 5-panel cups skip MDMA, but most 10/12-panel employment cups include it alongside amphetamines. MDMA structurally resembles amphetamine and shares the amphetamine assay family.
Molly pills frequently contain 'molly' substitutes (bath salts, cathinones) that standard panels also miss; conversely, confirmed MDMA positives cannot be explained away as contamination.
Detection is short — comparable to Adderall — because MDMA clears rapidly into MDA and inactive metabolites.
False positives & cross-reactivity
- High-dose fluoxetine or other amphetamine-cross-reactive drugs may flag the amphetamine portion of the assay; confirmation distinguishes true MDMA.
Frequently asked questions
How long does mdma (ecstasy/molly) stay in your system?
In urine, typical detection is 1–3 days (any use). Hair can detect use for up to 90 days and saliva/blood windows are usually shorter.
Will mdma (ecstasy/molly) show up on a standard drug test?
Yes — MDMA (ecstasy/molly) is screened on standard panels (10-panel, 12-panel).
Can anything cause a false positive for mdma (ecstasy/molly)?
High-dose fluoxetine or other amphetamine-cross-reactive drugs may flag the amphetamine portion of the assay; confirmation distinguishes true MDMA.
How accurate are these detection windows?
They are typical ranges from published literature and assay documentation, not guarantees. Clearance depends on dose, frequency, metabolism and the specific test cutoff used.
