Criminal justice client rehabs can be considered as a considerably better option than jail time or significant fines for those who have already been convicted of any type of drug or alcohol related crime. As an example, someone who has been found guilty of driving while impaired of drugs or alcohol may be eligible to get treatment services because of their problem instead of serving time in prison. The judge may even order that the individual receive treatment, either alone or together with other consequences. Very first time offenders in particular tend to be given the opportunity to go with a criminal justice client rehab rather than other sentencing, and it is highly recommended that they benefit from it if it is an alternative. The theory behind criminal justice client rehabs is it is much more effective and efficient to invest time and energy into rehab than punishment. Much research has been completed to discover how effective this approach 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 who do take part in rehabilitation have better potential for remaining out of the system following treatment.
