Quick info

Methylone (MDMC, 3,4-methylenedioxy-N-methylcathinone or βk-MDMA) is a synthetically produced amphetamine derivative. Methylone has a similar structure to MDMA, but belongs to the cathinone group. Methylone belongs to the group of new psychoactive substances. To date, little is known about the exact mechanisms of action, toxicity and possible long-term effects.
The effect is described as stimulating, euphoric, empathogenic and performance-enhancing. Compared to MDMA, methylone has a less empathogenic effect (less "feeling of connection"). The effect is often described as a mixture of amphetamine, cocaine and MDMA.

Methylone belongs to the group of new psychoactive substances. To date, little is known about its exact mechanisms of action, toxicity and possible long-term effects. The current state of knowledge is based almost exclusively on reports from users.
Short-term side effects include increased body temperature and heart rate, dilated pupils, and jaw tightening. Side effects and (long-term) risks of methylone are hardly researched.
