  JWH-372 (naphthalen-1-yl-[1-pentyl-5-[2-(trifluoromethyl)phenyl]pyrrol-3-yl]methanone) is a synthetic cannabinoid from the naphthoylpyrrole family which acts as a potent and selective agonist of the $CB_2$ receptor. JWH-372 binds approximately 9 times stronger to the $CB_2$ receptor $(K_i$ = 8.2 ± 0.2nM) than the $CB_1$ receptor $(K_i$ = 77 ± 2nM). The selectivity of JWH-372 for the $CB_2$ receptor is likely due to the electron-withdrawing character of the trifluoromethyl group rather than steric effects, as the o-methyl compound JWH-370 was only mildly selective for the $CB_2$ receptor $(CB_1$ $K_i$ = 5.6 ± 0.4nM, $CB_2$ $K_i$ = 4.0 ± 0.5nM).
  
  ## Legality
  
  In the United States JWH-372 is not federally scheduled, although some states have passed legislation banning the sale, possession, and manufacture of JWH-372.
  
  In Canada, JWH-372 and other naphthoylpyrrole-based cannabinoids are Schedule II controlled substances under the Controlled Drugs and Substances Act.
  
  In the United Kingdom, JWH-372 and other naphthoylpyrrole-based cannabinoids are considered Class B drugs under the Misuse of Drugs Act 1971.
