    Summary TheDrug.Wiki TripSit PsychonautWiki

    2-FMA is commonly described as a functional stimulant with clean mental effects and minimal peripheral side effects at oral doses below 40 mg. Potency is roughly one-half of amphetamine weight-for-weight. Higher doses introduce typical amphetamine side effects including tachycardia, vasoconstriction, bruxism, and anxiety. Vaporizing or smoking is strongly discouraged as decomposition above 200°C can liberate hydrogen fluoride, a corrosive and toxic gas. Use harm reduction practices including adequate hydration, magnesium supplementation for jaw tension, and deliberate meal planning.
