Extracts of 100 plant-like or resinous materials were analyzed for CBD, CBC, delta 9-THC, and CBN by GC using two different column packings and by GC-MS. Our independent identification of these cannabinoids confirmed those of other forensic science analysts who used microscopic examination, the Duquenois-Levine color test, and TLC for their analyses of the same samples. The identifications of cannabinoids by forensic acience analysts using TLC were corroborated by GC-MS analysis of hexane extracts of appropriate chromatogram spots.
