Criminal justice clients in Newcastle make their way into alcohol and drug rehabilitation centers due to the fact they were convicted of crimes relating to drugs, whether they were selling drugs or were in the possession of or high on drugs. Many judges put these convicted persons into the drug rehabilitation system mainly due to the fact that they consider that rehabilitating them is more effective for society and for the individual, rather than placing them in prison with no rehabilitation at all. This has been proven to be very effective not only in treating and rehabilitating these criminal justice clients in Newcastle, CA., but also in helping them stay sober and in many instances out of the criminal justice system permanently.
