Proposition 36 would increase the charge for theft to a felony for someone with two prior convictions for theft. It would also let judges sentence some drug dealers to state prison rather than county jail and increase the consequences for a dealer whose sale of fentanyl kills or seriously injures the user.

Supporters argue that tougher criminal penalties are needed to curb theft and the rising use of fentanyl. Opponents say that it will lead to an increase in the state’s prison population and the associated costs.
