Key Takeaways
- MDMA, chemically known as 3,4-methylenedioxymethamphetamine, has a molecular formula of C11H15NO2 and a molecular weight of 193.25 g/mol
- MDMA's half-life in humans averages 8-9 hours following oral administration of 1.5 mg/kg
- MDMA reversibly inhibits the serotonin transporter (SERT) with an IC50 of approximately 244 nM
- MDMA use among US 12th graders was 2.7% in the past year according to 2022 Monitoring the Future survey
- Lifetime MDMA use prevalence among US adults aged 18-25 is 10.2% per NSDUH 2021 data
- In Europe, 1.3% of young adults (15-34) reported past-year ecstasy use in 2022 EMCDDA report
- Hyperthermia occurs in 40-50% of MDMA-related hyperthermia cases leading to hospitalization
- MDMA-associated serotonin syndrome has a mortality rate of up to 11% in severe cases
- Chronic MDMA use is linked to 20-50% reduction in serotonin transporter density via PET imaging
- In MAPS Phase 3 trials, 67% of PTSD patients no longer met diagnostic criteria after 3 MDMA sessions
- MDMA-assisted psychotherapy reduces PTSD symptoms by 88% on CAPS scale in Phase 2 trials
- 83% response rate in social anxiety for autistic adults in MAPS pilot study with MDMA
- MDMA is classified as Schedule I under US Controlled Substances Act since 1985
- Global MDMA production estimated at 200-300 tons annually by UNODC 2023
- Australia rescheduled MDMA for PTSD therapy to Schedule 8 in 2023
MDMA therapy shows strong potential for PTSD while recreational use carries significant health risks.

How We Rate Confidence
Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.
Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.
AI consensus: 1 of 4 models agree
Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.
AI consensus: 2–3 of 4 models broadly agree
All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.
AI consensus: 4 of 4 models fully agree
