11-Hydroxy-Δ9-tetrahydrocannabinol (11-OH-THC), usually referred to as 11-hydroxy-THC, is the main active metabolite of tetrahydrocannabinol (THC), which is formed in the body after decarboxylated cannabis is consumed.[1][2]

Fresh cannabis contains tetrahydrocannabinolic acid (THCA), which is converted into THC after heating and then metabolized by the body into 11-hydroxy-THC and then into 11-nor-9-carboxy-THC;[2] both compounds can be glucuronidated and mainly excreted into urine. Both compounds, along with THC, are assayed in blood tests.[1]

11-hydroxy-THC has a similar psychoactive effect as THC, but with a slower onset of effect.[medical citation needed][3]
