Criminal justice client rehabs are available as being a significantly better option than time in jail or significant fines for individuals who have already been convicted of any type of drug or alcohol related crime. For instance, someone who has been found guilty of driving while impaired of drugs or alcohol may be eligible to get rehabilitation services for their problem as an alternative to serving time in jail. The judge may even order the individual receive rehabilitation, either alone or together with other sentencing. First-time offenders in particular in many cases are given the opportunity to go with a criminal justice client rehab as an alternative to other sentencing, and it is well-advised that they reap the benefits of it if it is an option. The concept behind criminal justice client rehabs is that it is way more effective and efficient to invest effort and time into rehabilitation than punishment. Much research has been done to find out how effective this approach is on recidivism rates, i.e. if the individual returns or not to criminal justice system following rehab. All indicators seem to be quite positive, and criminal justice clients that take part in rehabilitation have a much better possibility of remaining out of the system following rehab.
