Upgrades penalties for certain crimes involving heroin and fentanyl; establishes new crimes concerning heroin mixtures; allows certain defendants to be eligible for drug court.

This bill increases penalties for heroin and fentanyl-related crimes by lowering the quantity thresholds that trigger higher offense levels. For example, possessing 10 grams or more of heroin (previously 5 ounces) now constitutes a first-degree crime, while fentanyl-related offenses now require only 5 grams (previously 1 ounce) to reach the highest penalty level. The bill also establishes new criminal offenses for "heroin mixtures" (heroin combined with other controlled substances) and expands drug court eligibility to some first-degree offenders who are not drug distributors, allowing them to enter treatment programs instead of facing prison time. These changes aim to address the growing opioid crisis through both stricter penalties and expanded treatment options.
