Criminal justice client rehabs can be considered being a far better option than incarceration or heavy fines for individuals who have already been convicted of any kind of drug or alcohol related crime. For example, anyone who has been found guilty of driving while impaired of alcohol or drugs may be eligible for treatment services for their problem as opposed to serving time in jail. The judge might even order the individual receive rehab, either alone or together with other sentencing. First time offenders specifically will often be given the opportunity to select a criminal justice client rehab as opposed to other sentencing, and it is well-advised that they benefit from it when it is an alternative. The idea behind criminal justice client rehabs is that it is far more effective and efficient to invest effort and time into treatment than punishment. Much research has been carried out to find out how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. All indicators seem quite positive, and criminal justice clients that do take part in treatment have better probability of remaining out of the system after rehab.
