## Abstract A rapid and sensitive method for the simultaneous confirmatory analysis of three forensic most relevant cannabinoids, Δ^9^‐tetrahydrocannabinol (THC), 11‐hydroxy‐Δ^9^‐tetrahydrocannabinol (11‐OH‐THC) and 11‐nor‐9‐carboxy‐Δ^9^‐tetrahydrocannabinol (THC‐COOH), by means of high‐performance
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-
