JWH-250 (1-pentyl-3-(2-methoxyphenylacetyl)indole) is an analgesic chemical from the aminoalkylindole family, which acts as a cannabinoid agonist at both the CB1 and CB2 receptors, with a Ki of 11nM at CB1 and 33nM at CB2. Unlike many of the older JWH series compounds, this compound does not have a naphthalene ring, instead occupying this position with a 2'-methoxyphenylacetyl group, making JWH-250 a representative member of a new class of cannabinoid ligands.[2] Other 2'-substituted analogues such as the methyl, chloro and bromo compounds are also active and somewhat more potent.[3][4] It's rumored to be one of the cannabinoids in herbal blends such as Pandora Potpourri [5], that is quickly replacing K2 Blends in states where JWH-018 is being banned.

Samples of JWH-250 were first identified in May 2009 by the German Federal Criminal Police, as an ingredient in new generation "herbal smoking blends" which had been released since the banning of the original ingredients (C8)-CP 47,497 and JWH-018.[6]
