Complete dosage information for 2-FMA — threshold, light, common, strong, and heavy dose ranges across 2 routes of administration.
Full 2-FMA profileImportant Safety Notice
Dosage information is for harm reduction purposes only. Individual sensitivity varies greatly. Always start with the lowest effective dose and work your way up slowly. Never eyeball doses — use a milligram scale.
## Warning Signs Seek emergency medical attention immediately if you or someone else experiences any of the following after taking 2-FMA: - **Severe chest pain or pressure** -- the most dangerous sign, indicating acute cardiovascular strain - **Extremely rapid or irregular heartbeat** that does not slow with rest and calm breathing - **High fever or feeling dangerously overheated** -- hyperthermia accelerates all other toxicities - **Severe agitation, paranoia, or psychotic symptoms** -- persecutory thoughts, auditory disturbances, disorganized thinking - **Seizures** - **Loss of consciousness** ## What to Do **Call emergency services immediately (911 in the US, 999 in the UK, 112 in the EU).** Good Samaritan laws in most US states protect callers from prosecution for drug-related offenses when seeking help for an overdose. While waiting for help: 1. **Cool the person down** -- move to a cool environment, apply cold water or ice packs to neck, armpits, and groin. Hyperthermia is the single most dangerous amplifier of stimulant toxicity. 2. **Keep them calm.** Dim lights, lower noise, speak in a calm and steady voice. Physical restraint worsens hyperthermia and cardiac strain. 3. **If seizing**, protect their head and clear surrounding hazards. Do not place anything in their mouth. 4. **If unconscious and not breathing**, begin CPR. 5. **Offer water** if conscious and able to swallow. ## The Duration Problem **The critical difference between 2-FMA overdose and shorter-acting stimulant overdose is duration.** Symptoms may persist for 8-12 hours or longer due to the compound's extended pharmacokinetic profile. One Bluelight user reported 72 hours without sleep after doses totaling 100+ mg during a binge. Emergency departments should anticipate a prolonged clinical course. ## Hospital Treatment There is no specific antidote for 2-FMA overdose. Management is supportive: **benzodiazepines** (lorazepam, diazepam) for agitation, anxiety, and seizures. Active cooling for hyperthermia. Cardiovascular monitoring throughout -- the long half-life means cardiac effects may persist well beyond the resolution of behavioral symptoms. Beta-blockers are generally avoided with sympathomimetic overdose due to risk of unopposed alpha-adrenergic vasoconstriction.
A common insufflated dose of 2-FMA is 15–30 mg.
The threshold dose for 2-FMA via insufflated is approximately 5 mg.
2-FMA typically lasts 4–6 hours via insufflated.
2-FMA can be taken via insufflated, oral. Each route has different dosage ranges and onset times.
