Criminal justice client rehabs can be considered as being a considerably better option than time in jail or significant fines for many who have been convicted of any type of drug or alcohol related crime. For example, someone who has been found guilty of driving drunk of drugs or alcohol may qualify to receive rehabilitation services for their problem instead of serving time in prison. The judge may even order the individual receive rehabilitation, either alone or along with other consequences. First-time offenders specifically in many cases are given the ability to select a criminal justice client rehab rather than other sentencing, and it is well-advised they reap the benefits of it if it is a choice. The theory behind criminal justice client rehabs is that it is far more efficient and effective to invest effort and time into rehab than enforcement of other consequences. Much research has been done to find out how effective this strategy 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 that take part in rehab have a better chance of remaining out of the system following treatment.
