''[[Cannabis sativa]]'' L. is an intriguing plant that has been exploited since ancient times for recreational, medical, textile and food purposes. The plant's most promising bioactive constituents discovered so far belong to the [[terpenoid]] and [[cannabinoid]] classes. These specialized metabolites are highly concentrated in the plant aerial parts, and their chemical characterization is crucial to guarantee the safe and efficient use of the plant material irrespective of which use it is. This study investigates for the first time the use of vacuum-assisted headspace solid-phase microextraction (Vac-HSSPME) as a [[Sample (material)|sample]] preparation process in an analytical protocol based on Vac-HSSPME combined to fast [[gas chromatography–mass spectrometry]] (GC-MS) analysis that aims at comprehensively characterizing both the terpenoid and cannabinoid profiles of ''[[Cannabis]]'' [[inflorescence]]s in a single step ...

"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...)
