This is why I never understood the “commerce clause” controversy with Obamacare. If a product that CANNOT BE LEGALLY SOLD ACROSS STATE LINES is subject to Federal law due to interstate commerce, than anything falls under that umbrella.
Respondents Diane Monson and Angel Raich use marijuana that has never been bought or sold, that has never crossed state lines, and that has had no demonstrable effect on the national market for marijuana. 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.
