(a) In addition to any other taxes imposed upon the distribution of cigarettes under this part, there shall be imposed an additional tax upon every distributor of cigarettes at the rate of one hundred mills ($0.100) for each cigarette distributed on or after the first day of the first calendar quarter commencing more than 90 days after the effective date of this act.

(b) The board shall adopt regulations providing for the implementation of an equivalent tax on electronic cigarettes as that term is defined in subdivision (c) of Section 30121, and the methods for collection of the tax.

Such regulations may include, but are not limited to, defining who is a distributor of electronic cigarettes pursuant to Section 30011 and the licensing requirements of any such person.

(c) Notwithstanding any other provision of this part, all revenues resulting from the tax imposed by subdivision (a) and all revenues resulting from the equivalent increase in the tax on tobacco products, including electronic cigarettes, imposed by subdivision (b) of Section 30123, shall be deposited into the California Healthcare, Research and Prevention Tobacco Tax Act of 2016 Fund created by Section 30130.53.
