i don't see anywhere in the constitution where it gives the feds' the explicit authority to make plants illegal...

therefore, couldn't the supreme court have said THAT? and that it's a states' rights issue, and the states should decide if someone should be prosecuted.

there could be a federal law overturning the 1st amendment that's passed, would the supreme court have to uphold it?

the court doesn't have to be a rubber stamp, that's actually kind of a bad thing.
