Criminal justice client rehabs can be considered as being a significantly better option than jail time or significant fines for individuals who have already been convicted of any kind of alcohol or drug related crime. For instance, anyone who has been found guilty of driving drunk of drugs or alcohol may be eligible to get rehabilitation services for their problem instead of serving time in prison. The judge could even order that the individual receive rehabilitation, either alone or in addition to other sentencing. First time offenders in particular are often given the opportunity to choose a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended that they take advantage of it if it is an option. The idea behind criminal justice client rehabs is that it is much more efficient and effective to invest effort and time into rehab than punishment. Much research has been done to observe how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehabilitation. All indicators seem quite positive, and criminal justice clients that do take part in treatment have a better chance of remaining out of the system after rehabilitation.
