3-CEC

Human data are extremely limited; most information derives from small online self-reports and structural analogy to better-studied cathinones such as ethcathinone and 3-CMC. Meta-chlorinated cathinones have shown greater cytotoxicity in vitro compared with non-halogenated analogues; long-term neurotoxicity is plausible but unquantified. Pronounced vasoconstriction and hypertension observed; users with cardiovascular risk factors should avoid. Always confirm identity with reagent testing (Marquis reagent typically shows faint yellow-brown; Mecke shows olive-green) and ideally chromatography, as 3-CEC is sometimes mis-sold as 3-MMC or other cathinones. Due to short half-life, compulsive redosing is common; limit sessions to under 150 mg total, maintain hydration and electrolytes, supplement sleep, and allow at least 2 weeks between uses to reset tolerance and neurotransmitter stores.

Also known as: 3-chloroethcathinone, 3-Cl-ethcathinone, 3-chloro-NEC
