α-Pyrrolidinopentiophenone (or alpha-PVP), more commonly known as “flakka,” is part of the broad category of drugs called synthetic cathinones. Alpha-PVP first emerged in specific regions of the United States, receiving a lot of media coverage, particularly in Florida.

Like other synthetic cathinones, alpha-PVP has stimulant effects. There is almost no research available about alpha-PVP outside of experiments in animals.

Available reports regarding humans come largely from people who show up to emergency rooms with adverse effects, like agitation, aggression, violence and hallucinations, which are effectively treated with tranquilizers.
