JWH-081 is an analgesic chemical from the naphthoylindole family, which acts as a cannabinoid agonist at both the CB1 and CB2 receptors.[2] With a Ki of 1.2nM it is fairly selective for the CB1 subtype, its affinity at this subtype approximately 10x the affinity at CB2.[3] It was discovered by and named after Dr. John W. Huffman.

Legal Status[edit]

As of October 2015 JWH-081 is a controlled substance in China.[4]
