JWH-147

JWH-147 is an analgesic drug used in scientific research, which acts as a cannabinoid agonist at both the CB1 and CB2 receptors. It is somewhat selective for the CB2 subtype, with a Ki of 11.0 nM at CB1 vs 7.1 nM at CB2. It was discovered and named after the renowned professor of organic chemistry John W. Huffman.

Legal status
In the United States, CB1 receptor agonists of the 3-(1-naphthoyl)pyrrole class such as JWH-147 are Schedule I Controlled Substances.

JWH-147 was banned in Sweden on 1 October 2010 as harmful to health, after being identified as an ingredient in "herbal" synthetic cannabis products.
