Criminal justice client rehabs are available being a significantly better option than incarceration or significant fines for individuals who have already been convicted of any sort of drug or alcohol related crime. As an example, anyone who has been in prison for driving drunk of drugs or alcohol may be eligible to obtain rehab services for problem rather than serving time in prison. The judge might even order that the individual receive rehabilitation, either alone or in addition to other sentencing. Very first time offenders in particular in many cases are given the chance to pick a criminal justice client rehab instead of other sentencing, and it is well-advised they take advantage of it when it is an alternative. The theory behind criminal justice client rehabs is that it is way more effective and efficient to invest time and energy into rehab than punishment. Much research has been carried out to see how effective this strategy is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. All indicators seem quite positive, and criminal justice clients that experience rehabilitation have better potential for remaining out of the system after treatment.
