Crimes: controlled substances; crime of manufacturing, creating, delivering, or possessing with intent certain schedule 1 and 2 controlled substances; modify penalties. Amends sec. 7401 of 1978 PA 368 (MCL 333.7401).

SB 460 modifies Michigan's penalties for manufacturing, delivering, or possessing with intent to deliver certain controlled substances, primarily targeting Schedule 1 and 2 drugs (like narcotics and fentanyl derivatives). It establishes tiered penalties based on the substance's danger and quantity - for example, 1,000 grams or more of fentanyl or heroin now carries a potential life sentence or $1 million fine, while smaller amounts face reduced but still severe penalties. This directly affects individuals convicted of drug offenses under Michigan law, with specific provisions for fentanyl-related crimes and adjustments to prior sentencing structures.
