A gas chromatographic/mass spectrometric electron impact method is presented for the detection and quantification of 1 l-nor-9-carboxy-A9-tetrahydrocannabinol (THC-COOH) in urine, for use in the confirmation of presump tive results obtained by other techniques. Four extraction procedures, two solid-
Results obtained from three commercial immunoassay kits, Abuscreen, TDx, and EMIT, commonly used for the initial test of urine cannabinoids (and metabolites) were correlated with the 11-nor-delta 9-tetrahydrocannabinol-9-carboxylic acid (9-THC-COOH) concentration as determined by GC/MS. Correlation
