There is quite a lot of great research around medical cannabis. It's in large-scale human clinical trials that is really where the dearth of research is. We have to remember that we're talking about a plant that's been prohibited for almost 100 years, so for people who have been wanting to research it, it's been impossible to find a legal, consistent supply. Also, it's very onerous and takes an extremely long time to get licensing, even for laboratories.
One of the things this government can do, besides funding research, is to encourage, facilitate, and expedite it in any way that's in your power to do so.
