Biden wants to reschedule and decimalize not legalize
that means state by state determination
fifty different "united" states each with differing laws and opinions such as wages, what healthcare you are allowed and how it will be funded, abortion laws, immigration laws, what substances are legal or illegal or otherwise, etcetera
if you are on the wrong side of the state line then you will have less rights then your neighboring state
to go a step further there are already cities in the US where half the city has either medical use and or recreational use and the other half is strictly illegal or a combination there of such as half medical and half medical/ recreational and yes some tax and revenue the government receives from the cannabis industry goes towards prosecution of cannabis users in illegal places
Biden is only doing this for votes and knows the average voter will not know otherwise and we the people deserve better than a sham
These kind of laws and policies lessens consumer protections regarding cannabis while bolstering corporate cannabis and muddying the water further making the dream of legalization even more of a pipe dream
