Criminal justice client rehabs can be considered as a far better option than time in jail or heavy fines for individuals who have been convicted of any kind of alcohol or drug related crime. As an example, someone who has been in prison for driving while impaired of alcohol or drugs may be eligible to obtain rehab services for their problem rather than serving time in prison. The judge might even order the individual receive rehabilitation, either alone or along with other consequences. First-time offenders in particular tend to be given the opportunity to pick a criminal justice client rehab as an alternative to other sentencing, and it is well-advised they take advantage of it when it is an alternative. The theory behind criminal justice client rehabs is it is far more effective and efficient to invest time and energy into treatment than enforcement of other consequences. Much research has been completed to discover how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. All indicators appear to be quite positive, and criminal justice clients who do take part in treatment have a better chance of remaining out of the system following treatment.
