JWH-149 is a synthetic cannabimimetic that was discovered by John W. Huffman. It is the N-pentyl analog of JWH-148. It is a potent but only moderately selective ligand for the CB2 receptor, with a binding affinity of Ki = 0.73 ± 0.03 nM at this subtype, and more than six times selectivity over the CB1 subtype.[1]

In the United States, all CB1 receptor agonists of the 3-(1-naphthoyl)indole class such as JWH-149 are Schedule I Controlled Substances.[2]
