11-Hydroxy-Δ9-tetrahydrocannabinol, abbreviated as 11-OH-THC, is the main active metabolite of THC which is formed in the body after cannabis consumption. 11-Hydroxy-THC has been shown to be active in its own right, but the effects produced are not necessarily identical to those of THC. This might partially explain the biphasic effects of cannabis, whereby some effects such as increased appetite tend to be delayed rather than occurring immediately when the drug is consumed.
11-Hydroxy-THC is subsequently metabolised further to 11-nor-9-carboxy-THC, which is not psychoactive but might still play a role in the analgesic and anti-inflammatory effects of cannabis.
