Criminal justice client rehabs are available like a significantly better option than prison time or heavy fines for individuals who have already been convicted of any type of drug or alcohol related crime. For example, someone who has been in prison for dui of drugs or alcohol may qualify to obtain rehab services for their problem as an alternative to serving time in prison. The judge might order the individual receive treatment, either alone or along with other sentencing. First-time offenders in particular will often be given the ability to pick a criminal justice client rehab as opposed to other sentencing, and it is well-advised they make the most of it if it is an alternative. The idea behind criminal justice client rehabs is that it is way more effective and efficient to invest time and effort into treatment than punishment. Much research has been completed to find out how effective this strategy 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 who do experience rehab have better chance of remaining out of the system following rehabilitation.
