As of January 26, 2016, 5-DBFPV is deemed illegal in Sweden.

It’s important to note that 5-FDBFPV may potentially fall under the federal analogue act if utilized for human consumption, given its status as an analogue of Methylenedioxypyrovalerone.


1. What is 5-DBFPV?

  • 5-DBFPV, also known as 5-dihydro-benzofuran pyrovalerone and 3-deoxy-MDPV, is a stimulant drug in the cathinone class. It has been sold online as a designer drug.

2. How does 5-DBFPV differ from MDPV?

  • 5-DBFPV is an analogue of MDPV, with a specific structural change where the methylenedioxyphenyl group is replaced by dihydrobenzofuran.

3. Is 5-DBFPV legal in Sweden?

  • As of January 26, 2016, 5-DBFPV is illegal in Sweden.

4. What is the federal analogue act, and how does it relate to 5-DBFPV?
