While it is estimated that 8.5 percent of the general public aged 18 or older have substance use disorders, jails and prisons have a higher and disproportionate percentage of people with substance use disorders—53 percent and 68 percent respectively. Some of the challenges that incarcerated inmates with substance use disorders face are: they are less likely to make bail, more likely to have longer jail stays, more likely to experience victimization or exploitation, and more likely to serve time in segregation during incarceration. Further adding to these obstacles, when they are released from jail or prison, they lack access to services and may remain in a cycle of involvement with the criminal justice system. Based on research outcomes, the high percentage of substance use disorders in jails and prisons produces poor outcomes for both affected people and correctional agencies.
