Criminal justice client rehabs can be considered being a considerably better option than incarceration or significant fines for individuals who have already been convicted of any kind of alcohol or drug related crime. By way of example, a person who has been in prison for driving while impaired of alcohol or drugs may qualify to receive rehabilitation services for their problem as an alternative to serving time in jail. The judge could even order that the individual receive rehabilitation, either alone or in addition to other sentencing. Very first time offenders in particular are often given the opportunity select a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended that they benefit from it when it is an alternative. The theory behind criminal justice client rehabs is that it is way more efficient and effective to invest effort and time into treatment than punishment. Much research has been completed to observe how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. The signs and indicators appear to be quite positive, and criminal justice clients that do take part in treatment have a better chance of remaining out of the system following rehabilitation.
