Headspace volatiles of marihuana and hashish: gas chromatographic analysis of samples of different geographic origin. 1978

L V Hood, and G T Barry

The sweet odor of marihuana is of interest for instrumental monitoring of illicit drug traffic and for applications in forensic work. Headspace volatiles of marihuana and hashish of different origin are examined by gas chromatography, and relative compositions of 24 samples are compared. No correlation between volatile make up and geography was found, but the profiling procedures are shown to be of use in the forensic problem of relating samples to a common source.

D002849	Chromatography, Gas	Fractionation of a vaporized sample as a consequence of partition between a mobile gaseous phase and a stationary phase held in a column. Two types are gas-solid chromatography, where the fixed phase is a solid, and gas-liquid, in which the stationary phase is a nonvolatile liquid supported on an inert solid matrix.
