Criminal justice clients in Allston often end up in alcohol and drug rehabilitation programs because they were convicted of crimes relating to drugs, whether they were selling drugs or were in the possession of or under the influence of drugs. Many courts put these convicted persons into the alcohol and drug rehabilitation system mainly due to the fact that they believe that rehabbing them will be more helpful for society and for the person, rather than sending them in jail with no treatment at all. This has been established to be very successful not only in treating and rehabilitating these criminal justice clients in Allston, but also in keeping them sober and in a lot of situations away from the criminal justice system permanently.
