”Made legal.” Just throwing it out there that, in the country as founded, those things were not “illegal.” They were made illegal, by specious means (at the federal level). Wouldn’t a reschediling of marijuana, federally, just throw the matter back to the States, where it rightly (Constitutionally) belongs?
In the recent past Oregon tried the “legalization” scheme. It was initiated by a direct vote of the people, (democracy) and reversed by legislative action (representative republicanism) when it was found to be stupid.

Sadly, no; rescheduling reduces but doesn’t renounce federal control.
