4-CEC (4-Chloroethcathinone)
4-CEC (4-chloroethcathinone) is a ring-chlorinated synthetic cathinone stimulant that appeared as a designer replacement for banned cathinones. Human pharmacology is essentially unknown, documented only through forensic and case-report data.
01 Overview
4-CEC is the 4-chloro, N-ethyl analogue in the cathinone family and circulated on the research-chemical market as successively newer cathinones were banned. It is reported as a moderate stimulant with limited euphoria and pronounced redosing pressure.
No controlled human studies exist. Knowledge is limited to seized-material analysis and scattered intoxication reports, and it has been scheduled in several jurisdictions under new psychoactive substances legislation.
02 Mechanism
Presumed monoamine releaser and reuptake inhibitor with a stimulant-weighted profile, based on structural analogy to other 4-substituted cathinones.
