those 2 little amendments you posted prove that states are well within their power to prohibit drugs...Those two little amendments are not a grant of power. They are a limitation of it.
...just as the founders supported state laws that prohibited witchcraft, and sodomy...
They also supported slavery. Does that mean we should support slavery?
You startin to sound like a liberal. That's oranges and apples. The ones that supported slavery didn't view blacks as equal humans. However, the witchcraft and sodomy laws applied to everyone. And the very authors of the USC supported those state laws.
