Criminal justice clients in Hannibal make their way into drug rehabilitation programs because they were found guilty of drug related crimes, whether they were dealing drugs or had drugs in their possession or were under the influence of drugs. Some judges put these convicted individuals into the alcohol and drug rehab system mainly due to the fact that they consider that rehabilitating these persons is more effective for the culture at large and for the person, rather than placing them in prison with no rehabilitation at all. This has been established to be very effective not only in helping and rehabbing this type of client in Hannibal, but also in keeping them abstinent and in a lot of instances out of the criminal justice system for good.
