Criminal justice clients often need drug treatment because of their problems with drug and alcohol abuse. Due to the nature of the criminal justice system, there are specific steps and guidelines that must be completed in order to be accepted into a criminal justice substance abuse rehab center or recovery program. The initial step is to figure out the criminal justice clients eligibility. This step is accomplished by a panel of officials who decide how much and what type of treatment is necessary. Sometimes, the criminal justice clients obtain their substance abuse rehabilitation while they are incarcerated. For optimum results, they are encouraged, if not strictly directed, to continue their recovery process once they leave jail and enroll in sober living or a long-term residential transitional living program.
