Why does GW cultivate its own cannabis plants?
The absolute requirement for a plant-based medicine from a regulatory point of view is “control of starting materials”. A drug in its manufacture goes through many processes, each of which need to be monitored and strict quality controls applied. This process control and QC would be invalidated if the starting materials (i.e. the herbal materials) were of poor or inconsistent quality. Laboratory analysis of GW’s selected chemovar lines demonstrates that the cannabinoid ratios are very consistent. Such high levels of consistency are unusual in plants and are very important in applications made to medical regulatory authorities.
