N.J. Stat. § 2C:45-5
In the case of a person who is sentenced to probation in accordance with N.J.S. 2C:45-1, and who is ordered by the court as a condition of probation to undergo treatment for a substance use disorder involving drugs or alcohol, the temporary or continued management of a person's drug or alcohol dependency by means of medication-assisted treatment as defined herein, whenever supported by a report from the treatment provider of existing satisfactory progress and reasonably predictable long-term success with or without further medication-assisted treatment, the person's use of the medication-assisted treatment, even if continuing, shall not be the basis to constitute a failure to complete successfully the treatment program.
As used in this section, the term "medication-assisted treatment" means the use of any medications approved by the federal Food and Drug Administration to treat substance use disorders, including extended-release naltrexone, methadone, and buprenorphine, in combination with counseling and behavioral therapies, to provide a whole-patient approach to the treatment of substance use disorders.
