Proposition 56 was approved by voters in November 2016 to increase taxes on cigarettes and other tobacco products. Questions have been raised as to whether the Governor’s proposals for allocating Proposition 56 revenues meet the initiative’s requirement to supplement—and not supplant—existing spending in several areas. To examine these questions, we begin by reviewing the provisions of Proposition 56 and the Governor’s budget proposals. We then discuss whether the Governor’s proposals for Medi‑Cal could be viewed as supplanting General Fund resources and identify the relevant case law. We conclude by describing some trade‑offs for the Legislature to consider in allocating the Proposition 56 revenues.
