< | [[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 /> | |||

The [[cannabis]] market is expanding exponentially in the United States. As state-wide [[Legality of cannabis|legalization]] efforts increase, so also do demands for analytical testing methodologies. One of the main tests conducted on cannabis products is the analysis for [[Terpene|terpenes]]. This research focused on implementation of [[accelerated solvent extraction]] (ASE), utilizing surrogate matrix matching, and evaluation of traditional vs. more modern [[Sample (material)|sample]] introduction techniques for analyzing terpenes via [[gas chromatography–mass spectrometry]] (GC-MS) ...('''[[Journal:Accelerated solvent extraction of terpenes in cannabis coupled with various injection techniques for GC-MS analysis|Full article...]]''')<br /> | |||

[[Cannabis]]-related businesses (CRBs), in states where cannabis is legal, may be unable to obtain professional financial services such as banking, insurance, and accounting because of federal laws and regulations. This qualitative study investigated the following research questions: 1. Why are some certified public accountants (CPAs) unwilling to provide services to cannabis-related businesses? 2. How do CRBs compensate for lack of CPA services? 3. What does a CPA need to know about the cannabis industry prior to engaging to provide services to CRBs? Data for this grounded-theory qualitative study was gathered from twenty-three semi-structured phone and face-to-face interviews.

'''"[[Journal:Development of a gas-chromatographic method for simultaneous determination of cannabinoids and terpenes in hemp|Development of a gas-chromatographic method for simultaneous determination of cannabinoids and terpenes in hemp]]"''' | |||
An original [[Gas chromatography|gas-chromatographic]] method has been developed for simultaneous determination of major [[terpene]]s and [[cannabinoid]]s in plant [[Sample (material)|samples]] and their [[Cannabis concentrate|extracts]]. The main issues to be addressed were not only the large differences in polarity and volatility between both groups of analytes, but also the need for an exhaustive [[decarboxylation]] of cannabinoid acidic forms. Sample preparation was minimized by avoiding any analyte derivatization. [[Acetone]] was found to be the most appropriate extraction [[solvent]]. Successful chromatographic separation was achieved by using a medium-polarity column. Limits of detection ranged from 120 to 260 ng/mL for terpenes and from 660 to 860 ng/mL for cannabinoids.

The use of veterinary low-[[tetrahydrocannabinol]] (THC) ''[[Cannabis sativa]]'' (i.e., [[hemp]]) products has increased in popularity for a variety of pet ailments. Low-THC ''Cannabis sativa'' is federally legal for sale and distribution in the United States, and the rise in internet commerce has provided access to interested consumers, with minimal quality control. We performed an internet word search of “hemp extract and dog” or “CBD product and dog” and analyzed 29 products that were using low-THC ''Cannabis sativa'' extracts in their production of supplements. All products were tested for major [[cannabinoid]]s, including ∆9-tetrahydrocannabinol (THC), [[cannabidiol]] (CBD), [[cannabigerol]] (CBG), and other minor cannabinoids, as well as their respective carboxylic acid derivatives [[tetrahydrocannabinolic acid]] (THCA), [[cannabidiolic acid]] (CBDA), and [[cannabigerolic acid]] (CBGA) using an [[ISO/IEC 17025]]-certified [[laboratory]].('''[[Journal:Cannabinoid, terpene, and heavy metal analysis of 29 over-the-counter commercial veterinary hemp supplements|Full article...]]''')<br /> | |||
