Manufacturing facilities

Industry-leading facilities and process at GW Pharmaceuticals

High industry standards

Our manufacturing facilities and processes are compliant with Good Agricultural Practices and Good Manufacturing Practices. Both the premises and processes are regularly inspected and approved by relevant regulatory organisations including the Medicines and Healthcare products Regulatory Agency (MHRA), European Medicines Agency (EMA), US Food and Drugs Association (FDA), and the World Health Organization (WHO).

Tightly controlled growing conditions

Our scientists control all aspects of the plant growing cycle and environment. All GW plants are grown in a controlled, pesticide and contaminant-free environment. The plants are then processed, stored and quality tested continually.

Consistent quality, batch to batch

All our products are quality tested after purification and formulation to ensure quality and consistency at every step of the manufacturing process.
