CA SB1060

Adds fentanyl and oxycodone to controlled substances subject to additional mandatory prison terms based on weight thresholds, with terms ranging from 3 to 25 years depending on quantity.

Establishes weight thresholds for fentanyl enhancements starting at 20 grams (3-year term) up to 1,600 grams (25-year term), and includes oxycodone in existing heroin/cocaine enhancement provisions.

Requires courts to find circumstances in aggravation before imposing these additional penalties, reversing the prior standard that allowed courts to strike enhancements only upon finding mitigating circumstances.

Conspiracy enhancements only apply if the defendant conspirator was substantially involved in planning, direction, execution, or financing of the underlying offense.

Specifies that weight allegations must be charged in the accusatory pleading and admitted or found true by the trier of fact before enhancements can be imposed.
