Legal Status, Production, and Policy Interpretation
Pharmacological and Chemical Properties
- MDMA is the prototypical entactogen, chemically 3,4-methylenedioxymethamphetamine, with molecular formula C11H15NO2 and molecular weight 193.25 g/mol.
- MDMA has a pKa of 9.9 for its amine group, influencing its lipophilicity and blood-brain barrier penetration.
- Half-life of MDMA in plasma is approximately 8-9 hours after oral dose of 1.5 mg/kg.
- MDMA is primarily metabolized by CYP2D6 enzyme, with poor metabolizers showing 2-fold higher plasma concentrations.
- Peak plasma concentration of MDMA after 100mg oral dose is about 240 ng/mL at 2 hours post-ingestion.
- MDMA binds to serotonin transporter (SERT) with Ki=245 nM, causing reverse transport and massive serotonin release.
- Dopamine transporter (DAT) affinity for MDMA is Ki=1,800 nM, less potent than for serotonin.
- MDMA increases oxytocin release by 20-50% above baseline in humans after 1.5 mg/kg dose.
- Volume of distribution for MDMA is 5.2 L/kg, indicating extensive tissue distribution.
- MDMA undergoes O-demethylenation to MDA via CYP2D6, accounting for 10-20% of metabolism.
- Bioavailability of oral MDMA is nearly 100% due to first-pass avoidance in low doses.
- MDMA's chiral forms: S-(+)-MDMA is more potent, with 2-3x higher neurotoxicity than R-(-).
- Plasma protein binding of MDMA is low at 38%, allowing free fraction for CNS effects.
- MDMA inhibits monoamine oxidase (MAO) weakly, Ki>100 μM for MAO-A.

- MDMA EC50 for 5-HT release is 152 nM in rat synaptosomes.
- Active metabolite HHMA has similar potency to MDMA at SERT.
- MDMA logP (octanol-water) is 2.12, contributing to CNS penetration.
- Typical recreational dose of MDMA is 75-125 mg, with purity averaging 60-80% in street samples.

- Melting point of MDMA HCl is 148-150°C, used for purity identification.
- MDMA elevates mood via 5-HT2A receptor agonism secondary to serotonin flood.
