That's exactly what they are trying to do. Thing is it's virtually impossible to do that. In a bag of bush weed there are maybe 5-20 seeds. Each seed can be cloned limitless times. You can make the core raw material (cannabis oil) from that and alcohol. How can big pharma patent that?
Sure they'll try - but I can't see it working.
They may not be able to patent that, but they could, and would, produce it if it actually cured cancer.
You do realise a cure for cancer is the holy grail of medical research, right?
