And it should also be noted that what the US is moving toward is legalization (eliminating some or all prohibitions on drugs and making them not contraband, though there may be restrictions as with other legal medical drugs or recreational substances), not decriminalization (eliminating criminal penalties for small-quantity possession while maintaining the general prohibition such that the drug is still contraband.) While decriminalization has happened somewhere, state-level legalization of either medical use (making it, from a state perspective, analogous to other legal medical drugs, except with an ad hoc regulatory regime because it is still federally prohibited which prevents it from working with existing protocols for medical drugs) or more generally (making it more like, e.g., alcohol, with the same caveat) and there are currently-active proposals at the federal level for both medical and general legalization.
