Criminal justice client rehabs can be considered being a significantly better option than time in jail or heavy fines for many who have already been convicted of any sort of alcohol or drug related crime. For example, anyone who has been found guilty of driving under the influence of alcohol or drugs may be eligible to obtain treatment services for problem as opposed to serving time in jail. The judge may even order that the individual receive rehabilitation, either alone or in addition to other sentencing. First-time offenders in particular are often given the chance to go with a criminal justice client rehab as opposed to other sentencing, and it is highly recommended they take advantage of it if it's an option. The theory behind criminal justice client rehabs is it is way more efficient and effective to invest effort and time into rehabilitation than punishment. Much research has been carried out to find out 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 seem quite positive, and criminal justice clients that take part in treatment have a much better chance of remaining out of the judicial system following rehabilitation.
