A large data set from Washington (140,000 flower samples) is scrutinized here for evidence of consistently propagated strains with higher than a 2-to-1 ratio.
The U.S. Department of Agriculture (USDA) recently issued a temporary delay regarding enforcement on two provisions of its hemp regulations (1).
Commentary on how medicinal cannabis can evolve in a similar manner as the pharmaceutical industry did.
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.
An investigation of C18 and phenyl-hexyl column chemistries for definitive identification of 13 synthetic cannabinoid metabolites in patient samples.

Stell, the CEM product development lab manager; and Xiaoyan Wang, a research scientist at UCT
QuEChERS is introduced to the discipline of forensic testing as a viable method for the extraction of pesticides and cannabinoids in various complex sample matrices
Rapid Determination of 24 Synthetic and Natural Cannabinoids for LC–MS-MS Screening in Natural Products and Drug Inspection Applications
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.
