2F-QMPSB (SGT-13) is an arylsulfonamide-based synthetic cannabinoid that is a fluorinated derivative of QMPSB and has been sold as a designer drug.[1] Its identification was first reported by a forensic laboratory in Italy in January 2019,[2] and it was made illegal in Latvia shortly afterwards.[3][4] Fluorination of the tail group is a common strategy to increase potency at cannabinoid receptors which is seen in many related series of compounds.[5][6]
