Los Angeles County supervisors are hoping that a state ballot measure to legalize marijuana will pass in November so that they can tax it. The idea is part of their plan to fight homelessness – tax recreational pot to pay for homeless services. Previous ideas like a millionaire’s tax and a sales tax have fizzled. The measure to tax legal weed, which was approved by the Board of Supervisors Tuesday, comes two weeks after the LA City Council agreed to put a $1.2 billion initiative on November’s city ballot. The idea is that a three-pronged city-county-state strategy will help solve LA’s homeless crisis. Will it work?
