Criminal justice client rehabs are available as a significantly better option than time in jail or significant fines for individuals who have been convicted of any kind of alcohol or drug related crime. As an example, a person who has been in prison for driving drunk of alcohol or drugs may be eligible to receive rehab services because of their problem as an alternative to serving time in jail. The judge may even order that the individual receive rehabilitation, either alone or along with other sentencing. First-time offenders specifically tend to be given the ability to pick a criminal justice client rehab rather than other sentencing, and it is highly recommended that they make the most of it when it is an alternative. The idea behind criminal justice client rehabs is it is far more effective and efficient to invest effort and time into rehab than punishment. 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 rehabilitation. All indicators appear to be quite positive, and criminal justice clients who do take part in rehab have better possibility of remaining out of the system following rehabilitation.
