What Does MDMA Mean on a Drug Test? (Ecstasy)?

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

Quick answer: MDMA is the laboratory abbreviation for Ecstasy. MDMA/molly rides the amphetamine-family assay at 500/250 when included.

Reading your cup or lab report

Multi-panel cups print 2–4 letter codes beside each strip line. One line per drug class; a visible control line plus absent drug line = negative for that class. Faint lines still count as present (they're competitive-inhibition assays) — the classic misread.

About MDMA

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

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.

Detection windows

Ranges reflect occasional-to-heavy use patterns from FDA device inserts and SAMHSA-certified lab conventions.

Related codes on the same cup

Cups group codes logically: AMP/mAMP (stimulants), OPI/MOP/OXY/BUP (opioid family), BZO/BAR (depressants), COC/THC/PCP (classics), plus validity markers like creatinine printed on lab reports rather than cups.
