Criminal justice client rehabs can be considered being a far better option than incarceration or significant fines for individuals who have already been convicted of any kind of drug or alcohol related crime. By way of example, somebody who has been in prison for driving drunk of alcohol or drugs may be eligible to receive rehabilitation services because of their problem as opposed to serving time in jail. The judge may even order the individual receive treatment, either alone or in addition to other sentencing. New offenders in particular will often be given the chance to go with a criminal justice client rehab as opposed to other sentencing, and it is well-advised they benefit from it if it is an alternative. The theory behind criminal justice client rehabs is it is way more effective and efficient to invest time and energy into rehab 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 rehabilitation. The signs and indicators seem to be quite positive, and criminal justice clients who take part in rehabilitation have a better chance of remaining out of the system after rehab.
