Criminal justice client rehabs are available being a considerably better option than incarceration or heavy fines for many who have already been convicted of any sort of alcohol or drug related crime. As an example, someone who has been found guilty of driving under the influence of alcohol or drugs may qualify to get rehab services for his or her problem rather than serving time in jail. The judge could even order that the individual receive rehabilitation, either alone or along with other sentencing. First-time offenders in particular will often be given the opportunity pick a criminal justice client rehab rather than other sentencing, and it is well-advised they take advantage of it if it's a possibility. The theory behind criminal justice client rehabs is that it is way more efficient and effective to invest effort and time into treatment than punishment. Much research has been completed to see 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 appear to be quite positive, and criminal justice clients who experience rehab have better chance of remaining out of the system following rehabilitation.
