Efixii is the first platform of its kind for the medical cannabis industry. Its end-to-end solution – trademarked ‘Seed2Seed’ – is designed to enable medical professionals, cultivators, and regulator s to create better patient outcomes. The platform provides tools for every stage in the process to record best growing practices, certify compliance, enhance patient confidence, and improve the treatment experience. This is accomplished by leveraging multiple interlocking technologies, including mobile applications, artificial intelligence, smart databases, and an Ethereum blockchain.

Cannabis as a plant is highly variable by nature. To better understand the product, we verify eachgram’s lifecycle from cultivation to consumption via blockchain attestation. Thousands of resulting data sets provide clear evidence of “what happens to someone at a given point in time when a specific cannabis product is used to treat a specific symptom under a set of circumstances”. This data is processed by the company’s ‘Pain to Strain’ machine learning algorithm and can generate ‘averaged’ efficacy ratings on a per product-treatment basis. GCAC’s CitizenGreen Efixii technologies provide the medical cannabis data that cultivators need to create the best products, regulators need to write meaningful regulations, doctors need to write correct prescriptions, and patients need to confidently use products.
