Days after the Brooklyn District Attorney’s Office announced a program that could erase low-level marijuana convictions for thousands of people, Manhattan District Attorney Cyrus Vance Jr. moved to dismiss more than 3,000 open warrants for such cases Wednesday.

The low-level marijuana possession and public smoking cases date back to 1978, according to a news release. Vance appeared before Manhattan Criminal Court Judge Kevin McGrath to enter a motion to vacate the convictions.
