Slang for methcathinone.

A synthetic amphetamine derivative which is most similar in structure to methamphetamine and cathinone. Effects are similar to amphetamines but in high doses also has a resemblance to MDMA due to being a more potent serotonin reuptake inhibitor. Also has the rep for being very easy to synthesize making it novel for chemistry n00bs
Me: I just ate a quarter gram of MCAT and I feel great!
