We will examine the positive relationship between the state governments who write and enforce cannabis regulations and the private sector working in this new industry. One area in particular is the testing laboratory, whose test results provide increased confidence on behalf of patients, consumers, regulators and the public that the cannabis product label accurately reflects what the product actually contains. Besides tests for potency, most states crafted regulations detailing the characteristics medical or recreational marijuana must meet in order to be sold commercially (e.g., no or minimal pesticides, heavy metals, microbial contaminants, residual processing solvents) and that the specified cannabinoid and terpene profiles adequately and competently characterized. Often due to government funding/capacity issues testing is performed by commercial laboratories. So what is the glue between government needs to ensure safety and process transparency and the consuming public? The glue is the third-party accreditation body who themselves are evaluated by their peers to ensure that they meet ISO 17011 who assess to the most appropriate QMS standard: ISO 17025 for laboratory testing, ISO 17034 for cannabis reference material production, ISO 17043 for cannabis proficiency testing providers in of late a greater interest in certification bodies in accreditation to ISO 17065. Collectively these interlocking independent auditing systems helps instill confidence in the entire process to all, however the ISO 17025 standard is where these other standards come together in providing the necessary support for the creditability of the testing results. This presentation will detail common aspects of the ISO 17000-series standards and where they come together to help the laboratory’s accreditation to ISO 17025 in providing the critical assurance to customers and the public at large that the product testing performed in accredited laboratories has been to the highest standards.
