Medical Cannabis
A growing number of countries have implemented legal frameworks for the cultivation and use of medical cannabis. In December 2020, the UN recognized the medical value of cannabis. As a consequence, the market requires strict adherence to quality systems and cultivation procedures like compliance with guidelines such as the World Health Organisation (WHO) Good Agricultural & Collection Practices (GACP). Therefore, independent verification for compliance by third parties is becoming common practice in the industry. The CUMCS-GAP standard serves as a practical manual for Good Agricultural Practice (GAP) of medical cannabis anywhere in the world and allows for objective auditing by qualified auditors.
