That depends on when the person was convicted, as well as the specific charge. Those charged with simple possession of 4 ounces or less before Jan. 1, 2000, or from Oct. 1, 2015 through June 30, 2021 will be eligible to petition the Superior Court to have their criminal records erased — starting on July 1, 2022. Those charged with the same crimes between the period from Jan. 1, 2000 to Sept. 30, 2015 will have their records automatically erased starting on Jan. 1, 2023.
