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!

"A sustainable approach for the reliable and simultaneous determination of terpenoids and cannabinoids in hemp inflorescences by vacuum-assisted headspace solid-phase microextraction"

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 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 inflorescences in a single step ...

My 420 Tours guide.jpg
A fourth edition of Past, Present, and Future of Cannabis Laboratory Testing and Regulation in the United States has been released! This latest iteration updates many statistics, adds new regulation updates, and significantly updates many of the guide's resources such as the list of approved cannabis cultivators and testing laboratories. The update also adds additional context to standardization and accreditation efforts, including enforcement and quality subsections. It also adds a few more contextual bits of information about laboratory automation and its role in the cannabis testing lab.

I'm pleased to announce a new guide that has been released, the LIMS Buyer’s Guide for Cannabis Testing Laboratories. This guide recognizes the challenges of the current cannabis testing environment for laboratories and identifies the value of the laboratory information management system (LIMS) towards lessening the impact of those challenges on the cannabis testing lab. Not only does it address how the acquisition process should be approached and who the key players are, but it also addresses the current state of cannabis testing, and how well-implemented informatics can play a role towards a more efficient and compliant lab. Finally, an RFI for evaluating cannabis testing LIMS vendors is included to help you with the acquisition process. I hope you find this guide helpful!
