Harm Potential

Addiction & Dependence

Psychological

Moderate

Long-term use of 3-FMA is associated with moderate addiction risk, high abuse potential, and possible psychological dependence in some users. Abrupt discontinuation may be followed by cravings and withdrawal effects.

Toxicity

Cardiovascular

Due to putative serotonin-releasing properties, long-term use may potentially cause cardiotoxicity through excess 5-HT2B receptor activity, similar to effects seen with fenfluramine and MDMA; this risk remains theoretical and unstudied for 3-FMA specifically.

Psychosis Risk

Abuse at high dosages for prolonged periods can potentially result in stimulant psychosis presenting with paranoia, hallucinations, or delusions. Approximately 5-15% of users who develop amphetamine-induced psychosis fail to recover completely.

History & Culture

History & Culture not written up yet

Legality

International

Many jurisdictions are described as legally uncertain for 3-FMA, especially where analogue laws or intent-related facts matter.
