JWH-150
JWH-150 ((1-butyl-5-phenylpyrrol-3-yl)-naphthalen-1-ylmethanone) is a synthetic cannabinoid from the naphthoylpyrrole family which acts as an agonist of the CB1 (Ki = 60 ± 1nM) and CB2 (Ki = 15 ± 2nM) receptors, with a moderate (4x) selectivity for the CB2 receptor. JWH-150 was first synthesized in 2006 by John W. Huffman and colleagues to examine the nature of ligand binding to the CB1 receptor. Legality
In the United States JWH-150 is not federally scheduled, although some states have passed legislation banning the sale, possession, and manufacture of JWH-150. In Canada, JWH-150 and other naphthoylpyrrole-based cannabinoids are Schedule II controlled substances under the Controlled Drugs and Substances Act. In the United Kingdom, JWH-150 and other naphthoylpyrrole-based cannabinoids are considered Class B drugs under the Misuse of Drugs Act 1971. See also
