THJ 018 is an analog of JWH 018 where the core indole structure is substituted with an indazole base. Though no biological activity has been reported for THJ 018, structurally similar analogs bind to the brain central cannabinoid (CB1) receptors and display agonist properties in functional assays, suggesting that it would have the same in vivo effects as Δ9-THC and various synthetic CBs.
