Existing law, as added by the Substance Abuse and Crime Prevention Act of 2000, adopted by voters as Proposition 36 at the November 7, 2000, statewide general election, requires that persons convicted of certain nonviolent drug possession offenses be granted probation and participate in and complete an appropriate drug treatment program as a condition of that probation. After completion of drug treatment and the terms of probation, the act requires the court to conduct a hearing, set aside the conviction, and dismiss the complaint if the court finds, among other requirements, that the defendant successfully completed drug treatment. For purposes of the act, a defendant has successfully completed treatment if they have completed the prescribed course of drug treatment and, as a result, there is reasonable cause to believe that they will not abuse controlled substances in the future. The act allows its amendment by a statute passed by 2/3 of both houses of the Legislature and requires that all amendments further the act and be consistent with its purposes.
