Criminal justice clients in CA. make their way into drug rehab facilities due to the fact they were convicted of drug related crimes, whether they were selling drugs or were in the possession of or under the influence of drugs. Many courts put these convicted individuals into the alcohol and drug rehab system because they believe that rehabbing them is more productive for society and for the individual, rather than sending them behind bars with no treatment at all. This has been verified to be incredibly effective not only in treating and rehabilitating this type of client in California, but also in helping them remain sober and in a number of situations away from the criminal justice system for good.
