4-CMC sold as mephedrone
Risk assessment
A sample declared as 4-MMC (mephedrone) did not contain 4-MMC, but 4-CMC (4-chloromethcathinone; clephedrone).
4-CMC belongs to the group of New Psychoactive Substances (NPS) and is structurally related to 4-MMC. 4-CMC is described as having a strong performance-enhancing and euphoric effect. Some users report severe headaches as well as kidney and liver pain on the days following consumption. It is also reported that the substance can trigger a strong urge to re-dose, which increases the potential for addiction. 4-CMC is suspected of being highly neurotoxic.
There is hardly any information available on the effects, toxicity, side effects and long-term consequences of this substance. If you decide to consume this substance anyway, there are unknown risks involved. Regular use and high doses also increase the risk potential. Therefore, if you decide to use this substance anyway, we strongly advise you to follow the safer use messages / safer use tips. Due to a lack of information, the possible neurotoxic effect of 4-CMC and the associated risks that are difficult to assess, we advise against regular consumption.
With powders and crystals, false declarations occur time and again; it is therefore essential to have these substances tested!

Testing
If you do not have the possibility to have substances analysed, always test a small amount to avoid overdoses.

Wait 2 hours after oral intake, as there are always powders / crystals in circulation with unexpected active ingredients, which can have a later onset of action.
Utensils
When snorting or injecting powders, always use your own equipment to avoid infecting yourself or others with diseases.
