Criminal justice clients in Houston often end up in drug and alcohol rehabilitation centers because they were convicted of crimes relating to drugs, whether they were distributing drugs or were in the possession of or found to be high on drugs. Some courts put these criminal persons into the drug and alcohol treatment system because they feel that rehabilitating them will be more effective for society and for the person, rather than putting them in prison with no rehabilitation at all. This has been verified to be quite effective not only in treating and rehabilitating this type of client in Houston, but also in helping them stay off of drugs and in a lot of cases out of the criminal justice system for good.
