JWH-147 is an
analgesic drug used in scientific research, which acts as a
cannabinoidagonist at both the
CB1 and
CB2receptors. It is somewhat selective for the CB2 subtype, with a
Ki of 11.0 nM at CB1 vs 7.1 nM at CB2.[1] It was discovered and named after the renowned professor of organic chemistry
John W. Huffman.
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.[3][4]
