Two models for predicting time of last cannabis use from single plasma cannabinoid concentrations—model I, using Δ9-tetrahydrocannabinol (THC), and model II, using the concentration ratio of 11-nor-9-carboxy-THC (THCCOOH) to THC—were developed Bestehe einen Drogentest mithilfe von Hausmitteln – wikiHow Bestehe einen Drogentest mithilfe von Hausmitteln.
6158 individual urine specimens were screened by immunoassay with values ≥50 ng/mL classified as positive. Mini-Review 11-Nor-9-carboxy- 9-tetrahydrocannabinol a ubiquitous THC afford the non-psychoactive 11-nor-9-carboxy-THC (THC-COOH) as main metabolite. The pharmacokinetics of THC-COOH has been studied thoroughly and this abundant acid metabolite has become an established urinary marker of cannabis consumption in forensic, clinical and envi-ronmental analyses. Surprisingly, however, data on the biological 11-Hydroxy-THC - Wikipedia 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; both compounds can be glucuronidated and mainly excreted into urine. Both compounds, along with THC, are assayed in blood tests.

Δ9-Tetrahydrocannabinol (THC), 11-Hydroxy-THC, and Background: Δ9-Tetrahydrocannabinol (THC) is the primary psychoactive constituent of cannabis and an active cannabinoid pharmacotherapy component. No plasma pharmacokinetic data after repeated oral THC administration are available. Methods: Six adult male daily cannabis smokers resided on a closed clinical research unit.

It’s a metabolite of hydroxy that’s fundamentally inert, but which can linger in fat deposits for several weeks. For that reason, it’s the compound targeted by most urinalysis drug tests for cannabis.
