Criminal justice clients in Princeton make their way into drug treatment facilities because they were found guilty of crimes relating to drugs, whether they were selling drugs or were in the possession of or high on drugs. Some courts put these types of persons into the drug treatment system mainly due to the fact that they believe that rehabbing these persons will be more effective for society and for the person, rather than putting them in prison with no treatment at all. This has been verified to be quite effective not only in helping and rehabilitating this type of client in Princeton, but also in helping them stay sober and in many instances out of the criminal justice system once and for all.
