"Arizona and California have passed ballot initiatives that were
expected to divert minor, nonviolent drug offenders from incarceration to treatment? But what are the characteristics of imprisoned low-level drug offenders? Did the quantity or type of drug involved influence the prosecution pattern, and were there differences across racial groups in the prosecution of low-level drug offenders? This study is intended to fill those knowledge gaps."
