Criminal justice client rehabs can be considered as a considerably better option than jail time or heavy fines for those who have already been convicted of any sort of drug or alcohol related crime. For instance, anyone who has been found guilty of driving while impaired of drugs or alcohol may be eligible to get treatment services for their problem as an alternative to serving time in jail. The judge might even order that the individual receive rehabilitation, either alone or along with other sentencing. Very first time offenders in particular are often given the opportunity to pick a criminal justice client rehab instead of other sentencing, and it is highly recommended that they make the most of it if it is a choice. The concept behind criminal justice client rehabs is it is way more efficient and effective to invest time and effort into rehab than enforcement of other consequences. Much research has been completed to find out how effective this process is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. The signs and indicators appear to be quite positive, and criminal justice clients who do take part in rehabilitation have better probability of remaining out of the system after treatment.
