For nearly a century, [[Cannabis|cannabis]] has been stigmatized and [[Legality of cannabis|criminalized]] across the globe, but in recent years, there has been a growing interest in cannabis due to the therapeutic potential of [[Cannabinoid#Phytocannabinoids|phytocannabinoids]].

[[Cannabis]] and its secondary metabolite content have recently seen a surge in research interest. Cannabis [[terpene]]s and [[terpenoid]]s in particular are increasingly the focus of research efforts due to the possibility of their contribution to the overall therapeutic effect of [[Cannabis (drug)|medicinal cannabis]]. Current methodology to quantify terpenes in cannabis biomass mostly relies on large quantities of biomass, long extraction protocols, and long [[gas chromatography]] (GC) gradient times, often exceeding 60 minutes. They are therefore not easily applicable in the high-throughput environment of a cannabis breeding program. The method presented here, however, is based on a simple [[wikipedia:Hexane|hexane]] extract from 40 mg of biomass, with 50 μg/mL [[wikipedia:Dodecane|dodecane]] as internal standard, and a gradient of less than 30 minutes.

The diffusion of the legalization of [[cannabis]] for recreational, medicinal, and nutraceutical uses requires the development of adequate analytical methods to assure the safety and security of such products. In particular, [[aflatoxin]]s are considered to pose a major risk for the health of cannabis consumers. Among analytical methods that allow for adequate monitoring of food safety, [[wikipedia:Immunoassay|immunoassay]]s play a major role thanks to their cost-effectiveness, high-throughput capacity, simplicity, and limited requirement for equipment and skilled operators. Therefore, a rapid and sensitive [[wikipedia:Enzyme immunoassay|enzyme immunoassay]] has been adapted to measure the most hazardous [[wikipedia:Aflatoxin B1|aflatoxin B<sub>1</sub>]] in cannabis products.

Featured article of the month archive - 2020
Welcome to the CannaQAwiki 2020 archive for the Featured Article of the Month.
Featured article of the month: December 2020:"Screening for more than 1,000 pesticides and environmental contaminants in cannabis by GC/Q-TOF" A method has been developed to screen cannabis extracts for more than 1,000 pesticides and environmental pollutants using gas chromatography coupled to a high-resolution accurate mass quadrupole time-of-flight mass spectrometer (GC/Q-TOF). An extraction procedure was developed using acetonitrile with solid-phase extraction cleanup. Before analysis, extracts were diluted 125:1 with solvent. Two data mining approaches were used together with a retention-time-locked Personal Compound Database and Library (PCDL) containing high-resolution accurate mass spectra for pesticides and other environmental pollutants.
