Government regulation is constantly decreased. Weed is now legal in most US states for recreational use (I think; at any rate, many of them). The recent US Supreme Court Chevron decision will, for better or worse, probably lead to significant deregulation.
Weed is illegal everywhere in the US by federal law and defacto illegal by state law in most 'legal' states if you are anything other than a homeless bum, as driving a car with metabolites or owning a gun (or just living in same house) as a user are both crimes.
