Flakka (α-PVP), like other psychostimulants, can cause hyperstimulation, paranoia, and hallucinations. It has been reported to be the cause, or a significant contributory cause of death in suicides and overdoses caused by combinations of drugs. α-PVP has also been linked to at least one death with pulmonary edema and moderately advanced atherosclerotic coronary disease when it was combined with pentedrone.

α-PVP acts as a norepinephrine-dopamine reuptake inhibitor with IC50 values of 14.2 and 12.8 nM, respectively, similar to its methylenedioxy derivative MDPV.

α-PVP is a Schedule I drug in New Mexico, Delaware, Florida, Oklahoma, and Virginia. On January 28, 2014, the U.S. DEA listed it, along with nine other synthetic cathinones, on the Schedule 1 with a temporary ban, effective February 27, 2014. The temporary ban was then extended.
