Uh..No, I wasn't and am not. The question at hand was constitutional authority and drugs. Gonzales v Raich dealt with that question.
So you support the expansive Commerce Clause? You must, since you cited it for your argument. That's known as spitting on the Tenth Amendment. Read and learn from Justice Thomas:
If Congress can regulate this under the Commerce Clause, then it can regulate virtually anything–and the Federal Government is no longer one of limited and enumerated powers.
J. Thomas, dissenting in Raich
