Crimes: controlled substances; crime of manufacturing, delivering, or possession of with intent to deliver heroin or fentanyl; modify to reflect changes in sentencing guidelines. Amends sec. 7401 of 1978 PA 368 (MCL 333.7401).

SB 430 updates Michigan's sentencing for drug offenses involving heroin and fentanyl. It specifically increases penalties for these substances by setting life imprisonment as the maximum sentence for possessing 1,000 grams or more of heroin, fentanyl, or their derivatives - previously capped at 30 years for other drugs. The bill maintains lower penalties for smaller amounts (e.g., 50-450 grams carries up to 20 years) and for other controlled substances not listed in the enhanced provisions. This directly affects individuals convicted of manufacturing, delivering, or possessing these specific drugs with intent to distribute. The changes align sentencing for heroin/fentanyl with the most severe penalties under existing law, reflecting updated guidelines for these dangerous opioids.
