Criminal justice client rehabs can be considered as a far better option than prison time or heavy fines for many who have already been convicted of any sort of drug or alcohol related crime. As an example, someone who has been found guilty of driving drunk of drugs or alcohol may qualify to obtain treatment services because of their problem as an alternative to serving time in jail. The judge could even order that the individual receive treatment, either alone or together with other sentencing. First-time offenders specifically in many cases are given the opportunity to pick a criminal justice client rehab as opposed to other sentencing, and it is well-advised they take advantage of it if it is a choice. The concept behind criminal justice client rehabs is it is much more efficient and effective to invest time and energy into treatment than punishment. Much research has been carried out to observe how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. The signs and indicators appear to be quite positive, and criminal justice clients who take part in rehabilitation have a much better possibility of remaining out of the system after treatment.
