We describe a method for quantifying 11-carboxy-delta-9-tetrahydrocannabinol (THC-COOH) in meconium. After adding a labeled internal standard (THC-COOH D9) and acetonitrile, samples are sonicated to release both free and conjugated THC-COOH. The acetonitrile/aqueous layer is removed and mixed ...

The determination of 11-nor-delta9-THC-9-carboxylic acid (THC-COOH) in hair specimens at the sensitivity required to detect marijuana users is a difficult analytical problem. A sensitive and specific method has been developed for the quantitative assay of THC-COOH in hair. Hair specimens were ...

We recognized significantly lower Delta 9-THC-COOH concentrations for CYP2C9*3 (p = 0.001) and a trend of lower Delta 9-THC-COOH concentrations for CYP2C9*2 which did not reach statistical significance (p = 0.068). In addition, this study showed significantly higher values in the ratio ...

BACKGROUND: Whole blood, plasma and urine delta-9-tetrahydrocannabinol (THC), 11-hydroxy-THC (11-OH-THC) and delta-9-carboxy-THC (THCCOOH) concentrations document cannabis exposure. Clinical data generally are derived from specimens obtained after single THC administrations. Few data are available...
