An organisation that represents commercial farmers and agribusiness enterprises nationally has called for more research into the growing and trading of cannabis in SA and the rest of the world. In a market update on Monday, the Agricultural Business Chamber (Agbiz) said such research would assist policymakers in evaluating the benefits, and possible unintended consequences, of the plant. Agbiz noted a Constitutional Court ruling that decriminalised the private use of cannabis in SA. xxx.
