Hahahaha you really can't patent what already exists in nature.
This from Derek Lowe who has been writing the blog
in the pipeline for like 20 plus years. He pulls no punches when it comes to criticing Big Pharma. He has worked in the industry originally in hit to lead optimization forever. He is extremely well respected in the field is an editor for the ACS and advisor board for C&E news. Big Pharma only cares about stuff they can patent AND don't go belly up risking the cost of FDA approval vs failure (like a drug it takes 10 years of studies to prove it's effective).
If they can't patent it, it's useless to them ...
Big business can try to manipulate state laws so that only say medicinal is legal or outlaw home growing or make it legally damn near impossibile but big pharma has no skin in the game they can't profit off it
