Drug use rearrests up after Prop. 36: A UCLA study raises questions about the effectiveness of the law mandating treatment instead of jail time. (Megan Garvey and Jack Leonard, April 14, 2007, LA Times)

Convicted drug users in California are more likely to be arrested on new drug charges since Proposition 36 took effect than before voters approved the landmark law mandating drug treatment rather than incarceration, according a long-awaited study released Friday.

The state-funded study, conducted by UCLA researchers who have pored over four years of drug-related court cases, raises new questions about the effectiveness of Proposition 36 at a time when lawmakers and courts are discussing stricter requirements for defendants.
