Criminal justice client rehabs are available being a far better option than time in jail or significant fines for many who have already been convicted of any kind of alcohol or drug related crime. For example, someone who has been in prison for driving under the influence of alcohol or drugs may qualify to obtain rehab services for problem rather than serving time in jail. The judge could even order that the individual receive rehabilitation, either alone or together with other consequences. First time offenders in particular in many cases are given the chance to pick a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended they benefit from it if it's an option. The theory behind criminal justice client rehabs is it is way more effective and efficient to invest time and effort into rehab than punishment. Much research has been carried out to find out how effective this method 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 experience rehab have better chance of remaining out of the system after rehab.
