Criminal justice clients in Holyoke make their way into drug rehab facilities because they were found guilty of crimes relating to drugs, whether they were dealing drugs or had drugs in their possession or were under the influence of drugs. Some courts put these convicted persons into the drug and alcohol rehab system mainly due to the fact that they feel that rehabilitating them will be more productive for the culture at large and for the person, rather than putting them behind bars with no rehab at all. This has been verified to be incredibly successful not only in treating and rehabilitating these criminal justice clients in Holyoke, but also in helping them stay off of drugs and in a number of instances away from the criminal justice system for good.
