Welcome to Higher Law, our new weekly briefing about all things cannabis. I’m Cheryl Miller, reporting for Law.com from Sacramento, where our once reefer-hating senior U.S. senator, Dianne Feinstein, now says marijuana-legal states should be protected from the feds.

Feinstein says her views changed after talking to constituents. Facing a liberal opponent in her re-election bid this year probably helped too. Feinstein may not be the biggest legalization cheerleader, but she’s one less congressional roadblock for advocates.
