Summary
mCPP is widely considered unpleasant and dysphoric, inducing anxiety, headaches, and migraine attacks in susceptible individuals. It is occasionally sold as ecstasy or in party pills but lacks MDMA's euphoric effects. Individuals with personal or family histories of psychiatric disorders, panic disorder, or obsessive-compulsive disorder should avoid use as mCPP can exacerbate these conditions. CYP2D6 inhibitors including certain antidepressants and grapefruit juice significantly increase mCPP serum levels and risk of adverse effects. A reported fatality occurred in an individual with asthma who experienced a severe asthma attack after ingesting approximately 20mg of mCPP.
