Only upon a valid exemption certificate issued by the regulating government body, i.e. BAG, the manufacturer is allowed to plant, grow and harvest cannabis with medicinal use. But it is more than just gardening and cultivating the plant. A manufacturer has to follow the Good Agriculture and Collection Practice (GACP), a sub-part of the GMP regulations. GACP takes care of different aspects of a quality management system to provide plant and plant material which suffices the quality understanding of medicinal plants and allows a trace-back to the originating seed or seedling, including any manipulations on the plant during its growth. A comprehensive documentation regarding pre-defined quality aspects of the plant is one of the major parts of a compliant GACP approach.
