Some states that have legalized marijuana are considering providing so-called sanctuary status for licensed marijuana businesses, hoping to protect them from a shift in federal enforcement policy. Just hours after U.S. Attorney General Jeff Sessions announced on Jan. 4, 2018, that federal prosecutors would be free to crack down on marijuana operations as they see fit, Arreguin summoned a city councilman to his office with a novel idea on how to capitalize on the turmoil.
