I did a paper in uni decades ago that came to the conclusion that Marijuana be decriminalized. And this is long before all the findings about medial pot. Marijuana was made a schedule 1 drug for political reasons, out of fear, racism, protection of corporate profits, bad journalism, ignorance, incompetence and pushing personal political agendas.
Everything that is wrong about pot can be undone with just one step, making it a schedule 2 drug. Open up the doors for the growth and manufacture of Hemp for numerous uses- creating whole new industries. Raising in millions in tax revenues, emptying prisons, providing health benefits and so on. The idiocy of it being illegal is impossible to understand.
