Prosecutors in San Francisco will throw out thousands of marijuana-related convictions of residents dating back to 1975.
San Francisco District Attorney George Gascón said Wednesday that his office will dismiss and seal 3,038 misdemeanor convictions dating back before the state's legalization of marijuana went into effect, with no action necessary from those who were convicted.
Prosecutors will also review up to 4,940 felony convictions and consider reducing them to misdemeanors.
