Does MDMA Show Up on Urine test?

Evidence-based answer reviewed against SAMHSA cutoffs and FDA assay documentation · Updated August 2026

Quick answer: On a urine test, MDMA typically registers for 1–3 days after last use. ('Urine remains the employment default because it balances cost, window-length and legal defensibility. Metabolite CONCENTRATIONS (not presence/absence) decide results against cutoff tables, which is why hydration status moves numbers and why validity checks (creatinine, specific gravity) police dilution attempts.',)

How urine testing catches MDMA

('Urine remains the employment default because it balances cost, window-length and legal defensibility. Metabolite CONCENTRATIONS (not presence/absence) decide results against cutoff tables, which is why hydration status moves numbers and why validity checks (creatinine, specific gravity) police dilution attempts.',)

Urine: 500 ng/mL initial (when included); 250 ng/mL confirm (MDMA or MDA).

Context worth knowing

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.
