Criminal justice client rehabs are available as being a considerably better option than time in jail or heavy fines for those who have already been convicted of any kind of drug or alcohol related crime. For example, someone who has been in prison for driving drunk of alcohol or drugs may qualify to get rehab services for their problem as an alternative to serving time in prison. The judge might even order that the individual receive treatment, either alone or along with other consequences. First time offenders in particular tend to be given the chance to go with a criminal justice client rehab rather than other sentencing, and it is well-advised that they benefit from it when it is a choice. The idea behind criminal justice client rehabs is it is way more effective and efficient to invest effort and time into rehabilitation than punishment. Much research has been completed to find out how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following treatment. The signs and indicators appear to be quite positive, and criminal justice clients that do take part in rehab have a better potential for remaining out of the system following treatment.
