San Francisco dismissing thousands of old marijuana convictions

San Francisco will be "expunging or reducing misdemeanor and felony" marijuana convictions for the past several years, the San Francisco Chronicle reports, which could cost the state millions of dollars.

Why it matters: Recreational marijuana was legalized in 2016, and District Attorney George Gascón will be reviewing and erasing convictions "en masse" to avoid costly and time-consuming trials. He said the district attorney's office will "dismiss and seal more than 3,000 misdemeanor marijuana convictions ... dating back to 1975."
