Criminal justice clients in Lancaster, Massachusetts make their way into drug and alcohol rehabilitation programs because they were convicted of drug related crimes, whether they were dealing drugs or were in the possession of or under the influence of drugs. Many courts put these criminal persons into the drug rehab system mainly due to the fact that they believe that rehabbing these individuals is more helpful for society and for the individual, rather than placing them in prison with no rehabilitation at all. This has been verified to be extremely workable not only in helping and rehabbing these criminal justice clients in Lancaster, Massachusetts, but also in helping them remain abstinent and in a number of instances away from the criminal justice system once and for all.
