Criminal justice clients in Hercules, California make their way into alcohol and drug treatment centers due to the fact they were convicted of crimes relating to drugs, whether they were distributing drugs or were in the possession of or found to be high on drugs. Some courts put these criminal persons into the drug rehabilitation system mainly due to the fact that they believe that rehabilitating these individuals will be more effective for the culture at large and for the person, rather than placing them behind bars with no treatment at all. This has been verified to be quite successful not only in helping and rehabilitating these criminal justice clients in Hercules, but also in helping them remain abstinent and in many situations away from the criminal justice system for good.
