Criminal justice clients in Java often end up in drug and alcohol treatment programs because they were found guilty of drug related crimes, whether they were distributing drugs or were in the possession of or high on drugs. Some courts put these types of persons into the drug and alcohol treatment system mainly due to the fact that they believe that rehabbing them will be more productive for society and for the individual, rather than putting them in prison with no rehab at all. This has been verified to be incredibly workable not only in helping and rehabilitating this type of client in Java, but also in helping them remain sober and in a lot of situations away from the criminal justice system permanently.
