PB-22 is an analog of JWH 018 , a potent synthetic cannabinoid (CB) identified in smoking mixtures, that differs by having 8-hydroxyquinoline replacing the naphthalene group of JWH 018. FUB-PB-22 is a derivative of PB-22 in which the pentyl side chain is replaced by a 4-fluorobenzyl group, a functional group also found in the indazole-based synthetic CBs AB-FUBINACA and ADB-FUBINACA . The physiological and toxicological properties of this compound are not known. This product is intended for forensic and research applications.
