Aliases: 3-chloroethcathinone
Summary
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.
