Welcome to the CannaQAwiki 2022 archive for the Featured Article of the Month.

Featured article of the month: April 2022: "Does cannabis extract obtained from cannabis flowers with maximum allowed residual level of aflatoxins and ochratoxin A have an impact on human safety and health?" The aim of this study was to investigate whether the cannabis extract obtained from cannabis flowers that contain the maximum allowed level of mycotoxins affects human safety and health. For that purpose, a novel method of liquid chromatography with tandem mass spectrometry (LC-MS/MS) was developed and validated for the determination of aflatoxins and ochratoxin A (OchA) in cannabis extracts to demonstrate that this analytical method is suitable for the intended experimental design.

Products containing delta-8-tetrahydrocannabinol (Δ8-THC) became widely available in most of the United States following the 2018 Farm Bill, and by late 2020, those products were core products of hemp processing companies, especially where delta-9-tetrahydrocannabinol (Δ9-THC) use remained illegal or required medical authorization. Research on experiences with Δ8-THC is scarce, and some state governments have prohibited it because of this lack of knowledge. We conducted an exploratory study addressing a broad range of issues regarding Δ8-THC to inform policy discussions and provide directions for future systematic research. (Full article...) Featured article of the month: February 2022: "Fertilization following pollination predominantly decreases phytocannabinoids accumulation and alters the accumulation of terpenoids in Cannabis inflorescences" Over the last few decades, a growing body of evidence has increasingly showed the therapeutic capabilities of Cannabis plants. These capabilities have been attributed to the specialized secondary metabolites stored in the glandular trichomes of female inflorescences, mainly phytocannabinoids and terpenoids. The accumulation of these metabolites in the flower is versatile and influenced by a largely unknown regulation system, attributed to genetic, developmental, and environmental factors. As Cannabis is a dioecious plant, one main factor is fertilization after successful pollination. Fertilized flowers are considerably less potent, likely due to changes in the contents of phytocannabinoids and terpenoids. (Full article...) Featured article of the month: January 2022: "The cannabis terpenes" Terpenes are the primary constituents of essential oils and are responsible for the aroma characteristics of the Cannabis plant. Together with cannabinoids, terpenes illustrate a potential synergic and/or entourage effect, with their interactions having only been speculated on for the last few decades. Hundreds of terpenes have been identified that additionally add to the overall cannabis sensory experience, contributing largely to the consumer’s experiences, as well as the market price. These terpenes also enhance many therapeutic efforts, especially as aromatherapy. To shed light on the importance of terpenes in the cannabis industry, the purpose of this review is to morphologically describe sources of cannabis terpenes and to explain the biosynthesis and diversity of terpene profiles in different cannabis chemotypes.
