Well-established techniques used by the food safety industry, such as QuEChERS sample preparation followed by LC–MS/MS for the analysis of multiresidue pesticides, are evaluated for use with cannabis plant material.

Compact mass spectrometry, in combination with suitable sample introduction techniques-such as the atmospheric solids analysis probe, thin-layer chromatography, and classical liquid chromatography techniques-can be used effectively for the detection and quantification of cannabinoids and pesticides in cannabis-related material and contraband.

Other techniques for monitoring cannabinoids, such as GC–MS and LC–MS, are limited to screening known species and are therefore always one step behind the designer drug market-where new, previously unknown variations of analogs of cannabinoids are constantly being synthesized. The method presented here addresses this problem by providing accurate masses for all detected species, thus allowing postanalysis identification of initially untargeted compounds.
