Jun 01, 2005 · The aim of the present study was to develop a simple and sensitive LC–MS method for the estimation of Δ 8-tetrahydrocannabinol (Δ 8-THC) and its metabolite, 11-nor-Δ 8-tetrahydrocannabinol-9-carboxylic acid (11-nor-Δ 8-THC-9-COOH), in guinea pig plasma after topical drug application.The plasma samples were analyzed by LC–MS using negative-mode electrospray … The determination of 11-nor-delta9-tetrahydrocannabinol-9 ...
The main metabolite excreted in the urine is 11-nor-â £9-THC-9-COOH, which are found within hours of exposure and remain detectable in the urine for 3-10 days after smoking. The cutoff level for this 5 panel marijuana drug test is 50 ng/ml of 11-nor-D9-THC-9-COOH. Δ tetrahydrocannabinol and its metabolites 11- Δ9 ... tetrahydrocannabinol (THC-OH), which is psychoactive too [13–16], and THC-COOH it undergoes phase II biotrans-formation to a glucuronide conjugate [17]. About one third of the absorbed dose is excreted in the urine, about two thirds are eliminated via feces [18, 19]. Later it was suggested that urinary THC concentrations of more than E T DRUG COURT U PRACTITIONER I - National Drug Court ...

The derivatisation to the methyl ester was carried out using methyl iodide and mefenamic acid was used as internal standard. Detection of the Marijuana Metabolite 11-Nor-Δ9 ... Sep 01, 2006 · The GC-MS assay for the detection of THC-COOH in oral fluid was linear to 160 pg/mL with a limit of quantitation of 2 pg/mL. The detection of the marijuana metabolite, THC-COOH, in 76.2% of oral fluid specimens screening positive for cannabinoids is reported.
Δ9-Tetrahydrocannabinol (THC), 11-Hydroxy-THC, and 11-Nor ... In this study, we characterized free and glucuronidated plasma THC, 11-OH-THC, and THC COOH in daily cannabis users after self-administered smoked cannabis, after 20-mg oral THC, during 2–7 daily THC doses for 7 days, and for 22.5 h after last THC dose. Authentic plasma specimens stored at 4 °C were analyzed generally within 2 weeks. Urinary Elimination of 11-Nor-9-carboxy- 9 ...
The problem is that most current salivary tests are modified urine tests, and therefore detect THC-COOH.
Urinary Elimination of 11-Nor-9-carboxy- 9 ... The time course of 11-nor-9-carboxy-Δ[9] -tetrahydrocannnabinol (THCCOOH) elimination in urine was characterized in 60 cannabis users during 24 h monitored abstinence on a closed research unit for up to 30 days. 6158 individual urine specimens What is the difference between THC and THC-COOH? - Quora Aug 08, 2016 · THC-COOH is also known under various names such as 11-nor-9-carboxy-delta-9-THC, 11-nor-9-carboxy-delta-9-tetrahydrocannabinol, 11-COOH-THC, THC-COOH, and THC-11-oic acid.
