The chemical profile of ''[[Cannabis sativa]]'' L. female [[inflorescence]]s is rather complex, being characterized by a large number of molecules belonging to different chemical classes. Considering the numerous applications of [[cannabis]] in various fields—including the medical and pharmaceutical sectors, which have seen an increasing use for the ''Cannabis'' genus in recent years—a precise characterization of the matrices is essential. In this regard, the application of adequate and suitable [[Sample (material)|sampling]] and analysis techniques becomes important in order to provide an identification of the metabolites characterizing the profile of the sample under examination.

"Potency and safety analysis of hemp-derived delta-9 products: The hemp vs. cannabis demarcation problem"

Hemp-derived delta-9-tetrahydrocannabinol (Δ9-THC) products are freely available for sale across much of the USA, but the federal legislation allowing their sale places only minimal requirements on companies. Products must contain no more than 0.3% Δ9-THC by dry weight, but no limit is placed on overall dosage, and there is no requirement that products derived from hemp-based Δ9-THC be tested. However, some states—such as Colorado—specifically prohibit products created by “chemically modifying” a natural hemp component ... (Full article...)
