A proposed ballot measure that would legalize possession, use, growth and cultivation of marijuana would save the state of California hundreds of millions of dollars a year, according to a summary issued Thursday by the state attorney general's office.

The summary, which the office of Attorney General Kamala Harris, a Democrat, releases for each proposed ballot measure, says the state would save "in the low hundreds of millions of dollars annually" on law enforcement costs associated with enforcing marijuana laws.

As an added bonus, Harris's office said sales tax revenues could add more cash — again, in the "low hundreds of millions of dollars annually" — to the state's bottom line.
