Criminal justice clients in Castella, California make their way into drug rehab programs due to the fact they were convicted of drug related crimes, whether they were selling drugs or were in the possession of or high on drugs. Some judges put these convicted individuals into the drug rehabilitation system because they believe that rehabilitating them is more productive for the culture at large and for the person, rather than sending them behind bars with no treatment at all. This has been verified to be incredibly effective not only in helping and rehabilitating these criminal justice clients in Castella, but also in keeping them sober and in a number of cases out of the criminal justice system once and for all.
