4-CMC sold as 4-MMC
Risk assessment
These substances, known as 4-MMC (mephedrone) does not contain 4-MMC, but rather 4-CMC (4-chloromethcathinone; clephedrone).
4-CMC belongs to the cathinone group and is structurally related to 4-MMC (mephedrone). 4-CMC is described as having a strong performance-enhancing and euphoric effect. Some users report severe headaches and kidney or liver pain in the days following consumption. In addition, it has been reported that the substance can trigger a strong urge to take more, which increases its addictive potential. 4-CMC is suspected of being highly neurotoxic. No information is available on other risks, side effects, and long-term effects of 4-CMC. Due to the possible neurotoxic effects of 4-CMC, we advise against its use!
With powders and crystals, false declarations occur time and again; it is therefore essential to have these substances tested!
