Measurement of cannabinoid content, or “the potency test”, is frequently discussed in cannabis analysis. Many such methods have been developed in the past few years, but none have yet been rigorously validated and shown to work consistently with real cannabis samples of all types. Consequently, labs testing cannabis are each using different methods of analysis, and no standardized method has been universally adopted.
A study published in Scientific Reports titled The Cannabinoid Content of Legal Cannabis in Washington State Varies Systematically Across Testing Facilitys and Popular Consumer Products has highlighted the need for standardized laboratory methodologies in the legal cannabis industry. Authored by Nick Jikomes PhD (Principal Research Scientist with Leafly‘s Division of Data Science) and Michael Zoorob (Department of Government, Harvard University), and based on the complete I-502 dataset collected between the opening of Washington’s recreational cannabis market in 2014 through to May 2017, the study documents systematic differences in the cannabinoid content reported by different laboratories in the state. These differences persisted even after controlling for differences related to the producers, product types, or strain names of the samples being processed by each lab.
On February 21, our software development team attended Leaf Data System’s integrators meeting. Topics of discussion included ticketing, known errors, and the systems development life cycle.
Last month we talked about Myrcene as our Terp-In-Profile for the month of January. This month, let’s dig into the terpene Limonene and see what we can learn!
Everyone is talking about terpenes these days when it comes to cannabis – which is better than talking about just potency or cannabinoids, as the terpenes and the cannabinoids interact with each other to produce the unique effects we feel from each different strain we consume. This is the famous Entourage Effect, and to help people get familiar with all the wide variety of terpenes out there, we’re going to dig into a different terpene each month – January’s Terp-In-Profile is Myrcene!
UPDATE 2018-5-25: We have added a QR Code label template to our client portal – now you can print your product labels with a QR Code!
We’re feeling rather spiffy here at Confidence right now – our shiny new website is up and running! We’ve revamped to focus on the 3 things people look for most when they come to our site: pricing, FAQs, and blog posts. Our contact page is more comprehensive, and you can get our location information from the bottom of any page, whether you are on desktop or mobile. The Frequently Asked Questions section is now fully searchable so you can find the answers you need quickly. And of course, if you use our main site as your jump-point to our client portal, you can still get there with the Client Login button at the top right of the screen (or in the main site menu for those of you on mobile).
Seems like a simple question, doesn’t it? Clearly both have the same value, but 24 is different from 24.0 – in terms of implied precision, or certainty of the last digit.
Recently, we’ve taken calls from a few customers about the most recent LCB rule changes. There are a few concerns, and these rules are not exactly the easiest things to figure out. Let’s catch you up as we know it.
New cannabis QA testing requirements are on the horizon here in Washington state, taking effect on August 31, 2017. These rule changes mean adding new test requirements for some product types. Additional test requirements are going to mean increased testing costs for producers and processors. You can learn more about the new requirements on our New Rules FAQ page.
