Criminal justice client rehabs can be considered as a far better option than prison time or significant fines for many who have been convicted of any sort of drug or alcohol related crime. As an example, someone who has been found guilty of driving while impaired of drugs or alcohol may qualify for treatment services because of their problem as opposed to serving time in prison. The judge might even order the individual receive rehabilitation, either alone or in addition to other sentencing. First-time offenders in particular in many cases are given the opportunity to pick a criminal justice client rehab as opposed to other sentencing, and it is highly recommended they take advantage of it when it is an alternative. The concept behind criminal justice client rehabs is it is much more effective and efficient to invest effort and time into rehabilitation than enforcement of other consequences. Much research has been carried out to observe how effective this method 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 that do take part in rehab have better possibility of remaining out of the system after rehab.
