Criminal justice client rehabs are available as being a considerably better option than jail time or heavy fines for individuals who have been convicted of any type of drug or alcohol related crime. For instance, someone who has been found guilty of driving while impaired of alcohol or drugs may be eligible to get rehabilitation services for their problem as opposed to serving time in prison. The judge could even order that the individual receive rehab, either alone or along with other consequences. Very first time offenders in particular tend to be given the chance to go with a criminal justice client rehab rather than other sentencing, and it is well-advised that they benefit from it when it is an alternative. The theory behind criminal justice client rehabs is that it is much more effective and efficient to invest effort and time into treatment than punishment. Much research has been done to find out how effective this strategy is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. The signs and indicators appear to be quite positive, and criminal justice clients who experience rehabilitation have a better potential for remaining out of the judicial system after rehabilitation.
