This guide can help you if you are in jail or prison, on probation or parole, or involved in the Criminal Justice System (CJS) because of your alcohol or drug use. It provides you with information, strategies to cope with the challenges of recovery from a substance use disorder (SUD), and offers hope that you can change. No matter how chaotic your past, positive change is possible if you “work” a recovery plan and make good decisions to improve your life. This guide also provides suggestions on how you can work WITH a probation or parole officer.
