Criminal justice clients in Casanova often end up in drug treatment programs because they were found guilty of crimes relating to drugs, whether they were dealing drugs or were in the possession of or high on drugs. Some judges put these criminal individuals into the drug rehabilitation system because they believe that rehabbing them is more productive for society and for the individual, rather than placing them in prison with no rehab at all. This has been verified to be quite successful not only in treating and rehabilitating this type of client in Casanova, but also in helping them remain sober and in a lot of cases away from the criminal justice system for good.
