JWH-145 explained

JWH-145 (1-naphthalenyl(1-pentyl-5-phenyl-1H-pyrrol-3-yl)-methanone) is a synthetic cannabinoid from the naphthoylpyrrole family which acts as an agonist of the CB₁ (K_i = 14 ± 2nM) and CB₂ (K_i = 6.4 ± 0.4nM) receptors, with a moderate (~2.2x) selectivity for the CB₂ receptor. JWH-145 was first synthesized in 2006 by John W. Huffman and colleagues to examine the nature of ligand binding to the CB₁ receptor.^[1]

Legality

In the United States JWH-145 is not federally scheduled, although some states have passed legislation banning the sale, possession, and manufacture of JWH-145.^{[2] [3] [4]}

In Canada, JWH-145 and other naphthoylpyrrole-based cannabinoids are Schedule II controlled substances under the Controlled Drugs and Substances Act.

In the United Kingdom, JWH-145 and other naphthoylpyrrole-based cannabinoids are considered Class B drugs under the Misuse of Drugs Act 1971.
