I know that this can be more of a state and municipal issue rather than a federal one.
Sadly, it is a federal issue, whether we like it or not. Your state could make the hippie lettuce completely legal, and your municipality could then set up a community hemp farm and hash bar...
...and the FBI/DEA/ATF would swoop in, automatic weapons a-blazin', and take everyone into federal custody. And probably have the state and municipal goverments executed for treason.
Hooray for states' rights!
You are quite correct.
The voters in my state TWICE voted to reduce penalties on possession of small amounts of marijuana, and voted for medical marijuana, but the feds are blocking the will of the people.
