Criminal justice client rehabs can be considered being a significantly better option than prison time or significant fines for many who have already been convicted of any kind of drug or alcohol related crime. As an example, someone who has been found guilty of driving drunk of alcohol or drugs may be eligible to receive treatment services for his or her problem rather than serving time in prison. The judge may even order the individual receive treatment, either alone or in addition to other sentencing. Very first time offenders in particular in many cases are given the ability to pick a criminal justice client rehab rather than other sentencing, and it is highly recommended that they make the most of it if it is an option. The theory behind criminal justice client rehabs is that it is way more effective and efficient to invest effort and time into rehab than punishment. Much research has been done to see how effective this strategy is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. All indicators seem to be quite positive, and criminal justice clients who experience treatment have better potential for remaining out of the judicial system after treatment.
