Laboratory

Carboxy tetrahydrocannabinol Delta 9/Creatinine [Mass Ratio] in Urine

Definition

Carboxy THC is the major metabolite of cannabinoid found in urine, but is not related to source, time of exposure, amount, or impairment. Carboxy THC may be found in urine for 7-10 days following light or moderate use and as long as 4-6 weeks following heavy use. THC metabolites are stored rapidly in body fat following use and are released slowly over time. [https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3196989/]
