States can do whatever they want with respect to Prohibition. But I don't see anything in the US Constitution that says that the FedGov can regulate growing a plant. At least the prohibitionists of the early 20th century had the decency to pass a Constitutional Amendment when they wanted to ban drinking alcohol.

But then again, that silly Constitution doesn't really mean much anymore, does it?

Actually it’s not in the Constitution (which as a retired Marine) I would never call ‘silly”

But, the “plant” you are referring to has been deemed illegal, and tho there are those who say “it has no affect on mental performance” I would disagree. It might make you hungry, and happy, and I still don’t want to be driving on the same road with someone stoned.
