[[Cannabis sativa|''Cannabis sativa'' L.]] is an annual species cultivated since antiquity for different purposes. While in the past [[hemp]] [[inflorescence]]s were considered crop residues, at present they are regarded as valuable raw materials with different applications, among which extraction of the [[Cannabis concentrate|essential oil]] (EO) has gained increasing interest in many fields. The aim of the present study is the evaluation of the yield and the chemical composition of the EO obtained by [[Steam distillation|hydrodistillation]] from 11 hemp genotypes ...

The lack of scientific evidence of the safety and efficacy of over-the-counter topical [[cannabinoid]]-based cosmetics remains a concern. The current study attempted to assess the quality of cannabinoid-based cosmetic products available on the United Arab Emirates (U.A.E.) market. In particular, the study attempted to quantify the presence of undeclared [[tetrahydrocannabinol]]—specifically delta-9-tetrahydrocannabinol (Δ<sup>9</sup>-THC) and delta-9-[[tetrahydrocannabinolic acid]] (Δ<sup>9</sup>-THCA)—in these products.

[[Hemp]] ([[Cannabis sativa|''Cannabis sativa'' L.]]) [[cannabinoid]]s and [[Terpene|terpenoids]] have therapeutic effects on human and animal health. ''[[Cannabis]]'' plants can often have a relatively high heterogeneity, which leads to different [[phenotype]]s that have different chemical profiles despite being from the same variety. Little information exists about cannabinoid and terpenoid profiles in different hemp phenotypes within the same variety. For this study, 11 phenotypes from three different varieties—Carmagnola Selected (CS), Tiborszallasi (TS), and Finola Selection (FS)—were analyzed ...('''[[Journal:Metabolomic analysis of cannabinoid and essential oil profiles in different hemp (Cannabis sativa L.) phenotypes|Full article...]]''')<br /> | |||

Welcome to the CannaQAwiki 2021 archive for the Featured Article of the Month.
Featured article of the month: December 2021:South African cannabis-based products that were submitted to a private laboratory for the determination of heavy metals residues were analyzed. The presence of each heavy metal residue was determined in order to establish which residues are most prevalent in samples. Two specifications were considered for both oral as well as inhalation limits: United States Pharmacopeia (USP) <232>/<233> and the International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH) Q3D.
