PX-1 (also known as 5F-APP-PICA and SRF-30) is an indole-based synthetic cannabinoid that has been sold online as a designer drug.^[1]^[2]^[3]

Legality

Sweden's public health agency suggested classifying PX-1 as hazardous substance on November 10, 2014.^[4]

PX-1 is listed in the Fifth Schedule of the Misuse of Drugs Act (MDA) and therefore illegal in Singapore as of May 2015.^[5]
