Ensuring Quality and Consumer Safety
through State-of-the-Art Cannabis Testing




PSI is a center of excellence in cannabis science, testing, research and education.

PSI’s mission is to develop and implement evidence-based quality assurance processes in the fast-growing cannabis industry.

The cannabis industry is in great need of rigorous laboratory testing and product certification. PSI addresses this need with a multidisciplinary team of credentialed experts in plant science, medicine, food product testing, and business development. Our team uses state-of- the-art technology to provide a wide-variety of products and testing procedures to help ensure that cannabis consumers will safely enjoy the health benefits of cannabis under a variety of forms without financially burdening producers.




Phytoscience Consulting (PSC)

Phytoscience Consulting (PSC) provides consulting services to Cannabis and Hemp cultivators, producers, analytical laboratories, and dispensaries around the country. The PSC team has experience in targeted breeding techniques, cannabinoid extractions, product development, and delivery. PSC’s mission is to disseminate knowledge and best practices to improve product quality and safety in the cannabis industry across the country.


Product Certification (PSC)

Providing a product with a seal of approval can add value to that product by providing the assurance that it meets some basic criteria of excellence and safety for the consumer. There are currently no standardized labels for cannabis products. We see a need to assure the patient or consumer that the product is safe and meets the highest level of quality and safety with known and verified potency. PSI aims to standardize and label cannabis products in the U.S. by recommending a set of protocols for testing potency and safety. We then offer dispensaries, growers or producers the “Certified Cannabis” seal-of- approval if they meet the consensus statement criteria.


Research and Education

PSI is engaged in developing research studies and education programs that will advance product quality and consumer safety in the cannabis industry. To further our mission of bringing research-based education to the general public, PSI recently sponsored a Cannabis Speaker Series at the University of Vermont College of Medicine. The PSI team has also helped to develop and to teach the first medical cannabis course in the nation to be offered by an accredited medical school. 

PSI authored a white paper titled "Cannabis Testing for Public Safety – Best Practices for Vermont Analytical Laboratories” to aide the Vermont legislature in developing rules and regulations for ensuring the safety of the state’s medical cannabis program.
