Quick info

3-MMC is a synthetic cathinone from the amphetamine group and is closely related to mephedrone/4-MMC. The substance was developed as an analog after 4-MMC was banned and is one of the little-researched new psychoactive substances. In the meantime, 3-MMC has also been banned in most countries.
The effect is described as euphoric, empathogenic, relaxing, concentration- and performance-enhancing as well as stimulating. Compared to 4-MMC, 3-MMC has a less empathogenic effect (a "feeling of connection" as with MDMA, for example), but is more stimulating and libido-enhancing. The effect is often described as a mixture of amphetamine, cocaine and MDMA. In addition, especially when sniffing, the craving is very pronounced and the dependency potential is significantly higher than with other empathogens such as MDMA or methylone.

Risk
This combination already poses a significant risk. The effects can reinforce each other or change in unpredictable ways. Therefore, use these substances with caution, test new or unfamiliar substances individually first, and keep the doses as low as possible. Allow sufficient time between doses and avoid taking additional doses on a whim. Be aware of the varying durations of action for each substance.

Since 2023, cathinones such as 3-MMC have become more popular again. Drug checking services in Switzerland are increasingly accepting 3-MMC samples. The analysis results show that up to 75% of these samples contained synthesis by-products or (additional) ingredients other than the expected active ingredient. Cheap and/or legal, unexplored new psychoactive substances such as 3-CMC, 4-CMC or dimethylpentylone are often sold as 3-MMC.
