Welcome to CannaQAwiki, an encyclopedia for Cannabis and hemp, and the scientific and regulatory aspects that surround them. Welcome to CannaQAWiki. This wiki continues to be a work in progress, but new content is slowly being added. For example, check out the latest third edition of our guide Past, Present, and Future of Cannabis Laboratory Testing and Regulation in the United States. Additionally, the guide Starting a Cannabis Testing Laboratory has been updated for 2021, and the LIMSpec for Cannabis Testing has been released. Check back soon for additional content!

Get started New to CannaQAwiki? We're kind of new to this as well. In case you don't know where to begin, here are some starting points for you:   Our content so far... Our journal articles so far... Cannabis Cannabis (drug) Hemp Cannabinoid Terpene Seed-to-sale

Featured article of the month: June "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.

Articles and reference works Our wiki is young and will take time to grow. However, here are some of our important topical articles and guides, as well as reference works like lists and tables (which specifically appear in the "RefWork" namespace):   Topical articles and guides: NEW: LIMSpec for Cannabis Testing, 2021 Edition NEW: Starting a Cannabis Testing Laboratory, Second Edition Past, Present, and Future of Cannabis Laboratory Testing and Regulation in the United States, Third Edition Cannabis testing regulations in Canada Cannabis testing regulations in California Our reference works (so far): Known cannabis associations, organizations, and interest groups Known cannabis testing regulations in the United States Known licensed cannabis cultivators in North America Known licensed cannabis testing laboratories in North America Known vendors of cannabis testing instruments, software, and equipment

News and updates January 12, 2021: This is just a brief update to announce two things. First, the guide Starting a Cannabis Testing Laboratory has received a slight update for 2021. Some of the statistics were a little outdated, and some of the citations were broken. This update also tweaked grammar a bit more and added a few new sentences to clarify points. However, given that U.S. Federal legalization is still not a reality, most of the content still remains highly relevant, if not largely the same. Second, a specification document—LIMSpec for Cannabis Testing—developed for cannabis testing software systems, e.g., LIMS, has been released. It's largely derived from the base LIMSpec document on LIMSwiki but tweaked to address the needs of a cannabis testing laboratory. Hope you find these documents useful! Shawn Douglas (talk) 17:57, 12 January 2021 (UTC)       March 13, 2020: I'm pleased to announce that the third edition of Past, Present, and Future of Cannabis Laboratory Testing and Regulation in the United States is now complete. Started in 2017, the guide sought to provide a balanced look at the industry surrounding the Cannabis plant, particularly in the United States, with a strong focus on laboratory testing. As more U.S. states (and other countries) have legalized the plant's use, the cannabis industry continues to rapidly evolve in ways expected and unexpected. This third edition builds on previous material, adding more historical perspective on changing regulations, standards, and social impacts. It also adds timely topics such as how the insurance market is catering to cannabis companies, and it highlights new efforts to standardize not only laboratory testing but also accreditation of testing labs. One other major move: we've moved primary hosting to this wiki from LIMSwiki, a wiki similar in vein to this one but with a strong focus on laboratory informatics technology. Enjoy!
