General Effects NotesThe effects of 4-fluoromethcathinone are often compared to those of 4-methylmethcathinone (mephedrone), but with significantly less euphoria or feelings of empathy reported. Some users have noted that it feels "toxic", with lingering side effects such as headache, muscle tension and nausea.
Confusingly, both 4-FMC and, less frequently, its positional isomer 3-FMC have been referred to as "Flephedrone"; they seem to have similar effects.
Routes of AdministrationAs with other psychoactives, oral 4-fluoromethcathinone ingestion takes slightly longer to cause effects and lasts longer. Insufflation (snorting) is more associated with compulsive / addictive use patterns.
Addiction and Compulsive UseAs with 4-methylmethcathinone, compulsive use patterns that are similar to or stronger than those of other recreational euphoric stimulants have been reported. It is unlikely to be physically addictive, meaning that withdrawal symptoms are minimal and likely not life threatening, but psychological addiction seems likely to be a problem in some users with this substance.
EXPERIENCE EXCERPTS #
"[unspecified dose and ROA] While 4-fluoromethcathinone is reasonably useful as a stimulant at various dosages, there are well-studied pharmaceuticals that perform much better. 4-FMC always left me with a sort of "'so what?' feeling and no urge whatsoever to take my experiments further." -- "Study of Four Cathinones", Erowid Extracts Jun 2012;(22)10.
"[30-50 mg, insufflated / 100-200 mg, oral] 4-FMC turned out to be a valuable tool for increasing energy, motivation, and, to some degree, concentration. [...] For general stimulation, insufflated doses of 30Ð50 mg and oral doses of 100Ð200 mg seemed to work best." -- "Study of Four Cathinones", Erowid Extracts Jun 2012;(22)11.
"[150 mg, rectal] Still working on my music collection. It seems a bit like amphetamine in that it encourages mindless repetitive activity. In small doses it could be used as a study aid, perhaps. It is much less more a plain stimulant than mephedrone, methylone, bk-MBDB, less empathic. It is has a low quotient (but not zero) of entactogenic qualities. I feel no uncomfortably elevated heart rate or other signs of physical discomfort so I decide the dose may be too low." -- Exp 86047
"[repeated, oral, total ~400 mg] [...] pain and feelings of numbness in all extremities, intense tingling sensations and extreme sensitivity to touch, where even slight contact causes intense pain. Dizzyness, even feeling faintish periodically. Hand & feet freezing cold. Intermittent attacks of nausia. Unusually intense bodily (muscular) stiffness. Headache." -- Exp 84061
