Criminal justice client rehabs can be considered like a considerably better option than jail time or significant fines for those who have been convicted of any sort of drug or alcohol related crime. For instance, anyone who has been found guilty of driving drunk of alcohol or drugs may qualify for rehab services for their problem instead of serving time in jail. The judge may even order the individual receive rehab, either alone or together with other consequences. First-time offenders in particular tend to be given the chance to pick a criminal justice client rehab rather than other sentencing, and it is highly recommended they make the most of it if it is a possibility. The theory behind criminal justice client rehabs is that it is far more effective and efficient to invest effort and time into rehab than enforcement of other consequences. Much research has been carried out to discover how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehab. All indicators seem quite positive, and criminal justice clients who take part in treatment have better possibility of remaining out of the system after rehab.
