Biden only supported legalized medical marijuana, and to his credit, he did actually start the process to do that. He order rescheduling to schedule 3 which basically legalizes medical marijuana. It should go into effect around December as the DEA has dragged out the process
What he's saying is that a lot of the forces against recreational legalization are also against medical legalization, and moreover that a lot of the "moral crusade" against it is actually just cynical anti-competitive business tactics.
Or, [sigh], maybe that's just what I'm reading into it and he had no deeper point to make.
yes, pharmaceutical companies lose money when people use weed instead of pain pills, or any of the other pills that weed replaces. but advocates for private prisons also want weed to stay as a schedule 1, because that means more bodies in more cells costing more tax dollars. https://www.npr.org/sections/codeswitch/2014/03/13/289000532/why-for-profit-prisons-house-more-inmates-of-color
