Under which power can the feds legally claim a right to forbid the growing and selling of drugs within a state?

Well like others here have said, an amendment had to be passed to enact prohibition. And pot is a plant ferchrissake. At most, for interstate commerce purposes, the stuff could maybe be regulated when transported across state lines, strictly for control of agricultural disease.

But good luck now getting the FedGov to act within it's enumerated powers.

Actually you are being generous to the Commerce Clause abusers: The Commerce Clause is intended to prevent states from making laws that impede interstate commerce. You have to twist that intention pretty far to justify the WoD, and I think there is a good chance it would not survive a USSC look at a medical MJ case.
