JWH-018 is a full agonist synthetic cannabinoid with a high binding affinity to CB1 and CB2 cannabinoid receptors. JWH-018 has not been used in therapy. Many of the risks linked to cannabis use are also present in the case of JWH-018, among them complications in patients suffering from cardiovascular diseases and triggering of acute psychosis. JWH-018 has not been used in therapy. Studies in mice showed anti-inflammatory and cancer chemopreventive properties of JWH-018.
