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 />

"Development of a gas-chromatographic method for simultaneous determination of cannabinoids and terpenes in hemp"

An original gas-chromatographic method has been developed for simultaneous determination of major terpenes and cannabinoids in plant samples and their 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.
