Summary
4-Methylmethcathinone (also known as 4-MMC, M-CAT, drone, meow meow, and mephedrone) is a novel entactogen-stimulant substance of the cathinone class. Mephedrone belongs to a group known as the substituted cathinones, which are derivatives of the active ingredient in the khat plant (Catha edulluis). It is thought to produce its effects by promoting the release of the neurotransmitters serotonin, dopamine, and norepinephrine in the brain.
Perspectives
“This was a very enjoyable experience, and one which confirmed the reputation of mephedrone for short term effect and the temptation to sustain the euphoric high via compulsive redosing.”

User Experience
Tolerance
Tolerance Decay
Tolerance builds rapidly within and across sessions for monoamine‑releasing stimulants; user reports suggest partial cross‑tolerance with MDMA, amphetamines, and other cathinones. Data are anecdotal; schedule extended breaks (≥2 weeks) to reduce comedown and restore baseline.
