α-Pyrrolidinopentiophenone (also known as α-pyrrolidinovalerophenone, α-PVP, O-2387, β-keto-prolintane, prolintanone, or desmethylpyrovalerone) is a synthetic stimulant of the cathinone class developed in the 1960s that has been sold as a designer drug.
Colloquially, it is sometimes called flakka, or α-PVP is chemically related to pyrovalerone and is the ketone analog of prolintane.
Flakka (alpha-PVP), is a dangerous drug that is similar to the street drug commonly known as bath salts. Like other psychostimulants, it can cause hyperstimulation, paranoia, and hallucinations. α-PVP has been reported to be the cause, or a significant contributory cause of death in suicides and overdoses caused by combinations of drugs. It was a very popular drug used throughout Florida in 2014-2015, but has dwindled since that time period.
Flakka is typically white or pink in color, and is found in crystal form.
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.
