Criminal justice clients in Trenton make their way into drug rehab programs because they were convicted of crimes relating to drugs, whether they were dealing drugs or had drugs in their possession or were found to be high on drugs. Many courts put these criminal persons into the drug and alcohol rehabilitation system mainly due to the fact that they feel that treating them will be more helpful for society and for the individual, rather than sending them in jail with no rehabilitation at all. This has been established to be very effective not only in treating and rehabilitating this type of client in Trenton, but also in helping them stay abstinent and in many cases out of the criminal justice system for good.
