JWH-250 is a synthetic cannabinoid from the phenylacetylindole family. It acts as a cannabinoid receptor agonist, activating both CB1 and CB2 receptors, with high affinity that makes it psychoactive. Its chemical structure is noted for replacing the older naphthalene ring with a 2'-methoxy-phenylacetyl group, and related 2'-substituted analogues (like methyl, chloro, and bromo versions) are also active.

The compound was created by researcher John W. Huffman to study the endocannabinoid system. It first appeared in 2009 when German police identified it in new generation “herbal smoke” blends released after bans on earlier synthetic cannabinoids.

JWH-250 can be detected in urine using ELISA tests, underscoring its status as a substance of concern in drug testing.

Legally, JWH-250 is tightly controlled in many countries. Australia designates it as a Schedule 9 prohibited substance; the United States lists it as Schedule I; the United Kingdom classifies it as Class B; Canada as Schedule II; Germany as Anlage II; Brazil as a prohibited psychotropic (F2); and it is illegal in the Czech Republic and Latvia. Given its potential for abuse and health risks, it is not legal for general use.
