Criminal justice clients in Rancho Cucamonga, California make their way into drug rehabilitation programs due to the fact they were found guilty of crimes relating to drugs, whether they were distributing drugs or had drugs in their possession or were under the influence of drugs. Some courts put these types of persons into the alcohol and drug rehabilitation system because they feel that rehabilitating these persons will be more productive for society and for the person, rather than sending them in prison with no rehab at all. This has been proven to be incredibly workable not only in helping and rehabilitating this type of client in Rancho Cucamonga, but also in keeping them abstinent and in many instances out of the criminal justice system permanently.
