Criminal justice clients in St. Ann, Missouri often end up in drug rehabilitation centers because they were convicted of drug related crimes, whether they were distributing drugs or had drugs in their possession or were under the influence of drugs. Many judges put these types of individuals into the drug and alcohol rehab system mainly due to the fact that they believe that treating these persons will be more effective for society and for the person, rather than sending them in jail with no treatment at all. This has been proven to be very effective not only in helping and rehabilitating these criminal justice clients in St. Ann, Missouri, but also in helping them remain off of drugs and in a number of cases out of the criminal justice system for good.
