Nah, I was being sarcastic. I actually think your point is nonsensical. The Food & Drug Act is plainly a proper use of federal police powers under the Commerce Clause as properly applied, as opposed to the bastardization that liberals use now. Slapping the tenth amendment onto everything would render the supremacy clause meaningless. Theoretical future attempts to abrogate the second amendment is comparing apples to oranges.
MJ is federally prohibited under the Controlled Substances Act, which is based on the bastardized Wickard Commerce Clause that you rightly condemned and that liberals and gop-e have used to expand fedgov beyond its proper boundaries.
I’m going to guess that makes no difference to you and that you still support federal mj prohibition. Surprise me.
