Criminal justice clients in Parkman make their way into drug and alcohol rehabilitation programs because they were convicted of drug related crimes, whether they were dealing drugs or had drugs in their possession or were found to be high on drugs. Some courts put these convicted individuals into the drug and alcohol treatment system because they consider that rehabilitating these individuals is more helpful for society and for the person, rather than putting them behind bars with no rehab at all. This has been verified to be extremely effective not only in helping and rehabbing these criminal justice clients in Parkman, but also in helping them remain off of drugs and in a number of situations out of the criminal justice system for good.
