The bill amends New Jersey's drug laws to impose stricter penalties for crimes involving heroin and fentanyl, while also introducing new classifications for offenses related to "heroin mixtures," which are defined as substances containing heroin and at least one other narcotic. It raises the threshold for first-degree felony charges associated with significant quantities of these substances, mandating minimum prison sentences and substantial fines. Additionally, the bill modifies penalties for other controlled dangerous substances, categorizing offenses based on specific quantities and increasing maximum fines for first-degree crimes involving substances like LSD, PCP, methamphetamine, and marijuana. Notably, it clarifies the treatment of marijuana offenses for small quantities, allowing for written warnings for first-time offenders.

Furthermore, the bill enhances rehabilitation options by allowing certain defendants to be eligible for drug court and special probation, even for first-degree crimes under specific conditions. It establishes criteria for eligibility, emphasizing the need for professional assessments and compliance with treatment programs. The bill also outlines provisions for the expungement of records for individuals who successfully complete their special probation and treatment, provided they meet certain conditions. Overall, the legislation aims to balance public safety with the need for treatment and rehabilitation for individuals struggling with substance use disorders, while also providing pathways for reintegration into society through expungement opportunities.
