11-Hydroxy-Δ9-tetrahydrocannabinol (11-OH-THC) is the main active metabolite of Tetrahydrocannabinol (THC) which is formed in the body after cannabis is consumed.[1] The conversion from THC to 11-OH-THC is relatively high when cannabis is consumed in the form of cannabis edibles and, compared to oral consumption, lower when it is smoked or vaped.[2] 11-OH-THC is more potent than THC and crosses the blood–brain barrier more easily.[3][4] 11-Hydroxy-THC has been shown to be active in its own right.[5][6] 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.[7]
Fresh cannabis contains Tetrahydrocannabinolic acid (THCA), which is converted into THC after heating and/or 11-Hydroxy-THC.[8][9][10][11] Peak THC concentrations are lower after eating/drinking cannabis than after administration by smoking or vaping, but conversely, 11-OH-THC/THC ratios are higher after eating/drinking than after smoking cannabis.[12] After administration through eating or drinking, approximately equal quantities of THC and 11-OH-THC are formed, whereas 11-OH-THC is a minor constituent after administration by intravenous or smoking routes.[13] Because edible doses are processed by the liver before entering the bloodstream, THC consumed as edibles produces high levels of 11-OH-THC, while smoked cannabis, which goes directly from the lungs to the brain via the bloodstream and does not enter the liver,[14] produces lower levels.[15]
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.
