> Too bad things don't work that way, otherwise we'd have to arrest all the state governments that have approved medical or recreational use
Actually they do work that way.
And yes, the Fed has had a standoff with many States, and yanked funding for things in some cases. Also the DEA has been known to raid long standing medical marijuana clinics in CA. The current administration is a little lax on Marijuana, but that doesn't somehow make the law not apply here (The next administration could come down with a whip).
At the end of the day, there is no other way to slice it. Supporting marijuana in any capacity is currently against federal law.
