4-MMC (mephedrone)

Mephedrone causes euphoria and pleasant stimulation, an increased urge to talk, increased performance and altered sensory perceptions. It also stimulates the libido. The need for food and sleep is suppressed. The effect is also described as a mixture of MDMA, cocaine and amphetamine. 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. Compared to the similar 3-MMC, 4-MMC has a more empathogenic effect (a stronger "feeling of connectedness" as with MDMA, for example), but is less stimulating and uplifting.
