Tweed technologists refine THC testing


At Tweed, our devotion to transparency is tantamount to our commitment to customer service and great product offerings. Since the gates to our Smiths Falls plant first swung open in 2014, we’ve maintained an open door policy, inviting everyone from patient groups to the international press to learn about our grass and grow methods.

In areas of operation where some Licensed Producers (LPs) have played it close to the chest, we’ve given unfiltered access to anyone curious enough to ask. Particularly, where the contentious topic of sampling methodologies is concerned, Tweed has taken measures to not only be open to our customers, but accountable to the entire industry.

Over the last number of months, our scientists have been refining a method for testing cannabinoids using a High Performance Liquid Chromotograph instrument that ensures the pinpoint accuracy of our THC and CBD percentages. Today, we’re pleased to announce that the method has been validated, meaning we can now test our products and cannabis from any other licensed company.

Ben Geiling is excited by that prospect. As the company’s Scientific Developmental Technologist, he sees the daily experiments being conducted in the Tweed lab as potential long-term solutions to some of the pressing questions that continue to cloud this new industry in controversy.

“The method that we use in-house to test dried marijuana for potency has been validated and what that means is we’ve shown through a series of experiments that our test results are accurate,” he says. “To do that, there’s a lot of technical details that require statistical analysis and experiments that we have to perform just to show that this method yields reproducible, accurate and precise results.”

Tweed’s Director of Quality Assurance, Tom Shipley, says the method we’ve developed to test our cannabinoids brings together the best practices in the industry, resulting in a better testing method than any that has yet been published.

“In the end, we ended up getting something that has better separation and resolution of cannabinoid compounds compared to other testing methods, even ones utilized by national testing facilities,” says Shipley. “Having a test method published in the European Pharmacopeia or United States Pharmacopeia is where the cannabis industry’s heading.”

Because there isn’t currently a guideline for measuring cannabinoids in the United States Pharmacopeia or the European Pharmcopoeia – two manuscripts that contain the best available scientific evidence surrounding herbal drugs and medicine – the analytical method we have developed could serve as the standard method for how cannabinoids are tested in this country.

Even if our process is never published or patented for application across the industry, he says the in-house method we’ve developed will allow Tweed to stand behind its numbers with confidence. Because we will perennially have the proper checks and balances in place, Shipley says our customers can be sure the numbers we report are correct and consistent.

“By doing our tests in-house, we have full control of the checks in place to make sure the results are accurate, the equipment is functioning properly and the sample is fully traceable” he says. “We know what goes in, we know the right controls are in place and we have full visibility to ensure our tests are the most exact in the industry.”
