JWH-307
JWH-307 is an analgesic drug used in scientific research, which acts as a cannabinoid agonist at both the CB and CB receptors. It is somewhat selective for the CB subtype, with a K of 7.7 nM at CB vs 3.3 nM at CB. It was discovered by, and named after, John W. Huffman. JWH-307 was detected as an ingredient in synthetic cannabis smoking blends in 2012, initially in Germany. In the United States, CB receptor agonists of the 3-(1-naphthoyl)pyrrole class such as JWH-307 are Schedule I Controlled Substances.
