Criminal justice clients in Mission Viejo, California make their way into alcohol and drug treatment programs because they were convicted of crimes relating to drugs, whether they were selling drugs or had drugs in their possession or were under the influence of drugs. Some courts put these convicted individuals into the alcohol and drug treatment system because they believe that rehabbing these individuals is more effective for society and for the individual, rather than sending them in prison with no treatment at all. This has been established to be quite effective not only in helping and rehabbing these criminal justice clients in Mission Viejo, but also in keeping them abstinent and in a lot of cases out of the criminal justice system permanently.
