JWH-133 is a potent selective CB₂ receptor agonist with a Ki of 3.4nM and selectivity of around 200x for CB₂ over CB₁ receptors. It was discovered by and named after, John W. Huffman.

JWH-133, alongside WIN 55,212-2 and HU-210, is responsible for preventing the inflammation caused by Amyloid beta proteins involved in Alzheimer's Disease, in addition to preventing cognitive impairment and loss of neuronal markers. This anti-inflammatory action is induced through agonist action at cannabinoid receptors, which prevents microglial activation that elicits the inflammation. Additionally, cannabinoids completely abolish neurotoxicity related to microglia activation in rat models.

It may be linked with anti-cancer properties, according to pre-trial data from a 2010 study in Madrid.

The substance commonly referred to as "JWH-133" is not a scheduled substance in the U.S, except in Alabama. Low abuse potential makes it less likely for regulation relative to its sister drugs such as JWH-018, as JWH-133 is selective for the non-psychoactive CB₂ receptor and thus lacks significant psychoactive effects.
