Criminal justice client rehabs are available as a far better option than time in jail or significant fines for individuals who have been convicted of any kind of drug or alcohol related crime. By way of example, anyone who has been in prison for driving while impaired of alcohol or drugs may be eligible to get rehab services for their problem rather than serving time in prison. The judge may even order that the individual receive rehabilitation, either alone or together with other sentencing. Very first time offenders in particular are often given the chance to go with a criminal justice client rehab rather than other sentencing, and it is highly recommended that they benefit from it when it is a possibility. The idea behind criminal justice client rehabs is it is far more efficient and effective to invest time and energy into treatment than punishment. Much research has been carried out to see how effective this method is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. All indicators seem quite positive, and criminal justice clients that take part in treatment have a much better probability of remaining out of the system after treatment.
