§ 04 — SCIENCE

4-MMC (mephedrone) emerged as a popular new psychoactive substance in the late 2000s, marketed initially as a 'legal high' and MDMA substitute before being banned across most jurisdictions. Clinical case reports document sympathomimetic toxicity including palpitations, chest pressure, tachycardia, and hyperthermia following recreational use. Animal studies indicate strong dopaminergic and serotonergic activity, with a pharmacological profile intermediate between amphetamine and MDMA. Human pharmacokinetic data remain limited; most evidence derives from user self-reports, toxicological case findings, and forensic analyses. Postmortem studies show 4-MMC is unstable in putrefied biological matrices, complicating forensic quantification. The compound's short half-life and rapid clearance may drive compulsive re-dosing patterns and elevated dependence risk compared to longer-acting stimulants.
