Criminal justice client rehabs can be considered being a significantly better option than incarceration or heavy fines for individuals who have already been convicted of any kind of alcohol or drug related crime. For example, anyone who has been found guilty of driving drunk of alcohol or drugs may qualify to receive rehabilitation services for their problem rather than serving time in jail. The judge could even order that the individual receive rehabilitation, either alone or along with other consequences. First-time offenders in particular will often be given the opportunity to choose a criminal justice client rehab instead of other sentencing, and it is well-advised that they take advantage of it when it is a choice. The idea behind criminal justice client rehabs is it is far more effective and efficient to invest time and energy into rehab than enforcement of other consequences. Much research has been done to see how effective this method is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. All indicators appear to be quite positive, and criminal justice clients that experience rehab have a much better chance of remaining out of the system after rehab.
