Criminal justice client rehabs are available as a significantly better option than jail time or significant fines for individuals who have been convicted of any sort of alcohol or drug related crime. By way of example, anyone who has been in prison for driving while impaired of alcohol or drugs may qualify to receive rehabilitation services for his or her problem as opposed to serving time in jail. The judge could even order the individual receive rehabilitation, either alone or along with other sentencing. First time offenders specifically in many cases are given the ability to select a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended that they take advantage of it if it's an alternative. The concept behind criminal justice client rehabs is that it is much more effective and efficient to invest effort and time into rehab than enforcement of other consequences. Much research has been done to find out how effective this process is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. The signs and indicators seem quite positive, and criminal justice clients who take part in rehab have a better chance of remaining out of the system after rehabilitation.
