Assembly member Tom Ammiano (D-San Francisco) has introduced legislation to implement Proposition 19 in the event that the initiative passes on November 2. Proposition 19 allows the legislature to amend it by a majority vote as long as it is in line with the goals of the initiative. The Regulate, Control and Tax Cannabis Act, ABX6-9, establishes a uniform statewide regulatory system while retaining a local option for sales. It also specifically excludes medical marijuana from fees and regulations in the act.

"Proposition 19 is an opportunity for Californians to finally change direction after years of our failed 'war on drugs,' said Ammiano. "But no initiative is perfect and the devil is in the details. My bill gives the legislature the ability to fine tune how California will regulate cannabis to ensure that it is done in an effective, systematic way." - Tom Ammiano
