Criminal justice client rehabs can be considered being a far better option than prison time or significant fines for individuals who have already been convicted of any kind of alcohol or drug related crime. As an example, anyone who has been in prison for driving while impaired of drugs or alcohol may be eligible to get rehabilitation services for his or her problem rather than serving time in jail. The judge could 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 go with a criminal justice client rehab as an alternative to other sentencing, and it is well-advised they take advantage of it if it is a possibility. The concept behind criminal justice client rehabs is it is much more effective and efficient to invest effort and time into rehabilitation than punishment. Much research has been done to see how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. All indicators appear to be quite positive, and criminal justice clients that experience rehab have a better probability of remaining out of the system following treatment.
