Criminal justice clients in Harlingen make their way into alcohol and drug treatment centers due to the fact they were convicted of crimes relating to drugs, whether they were selling drugs or had drugs in their possession or were found to be high on drugs. Some courts put these convicted individuals into the drug rehabilitation system because they consider that treating them will be more effective for society and for the person, rather than placing them in prison with no rehabilitation at all. This has been established to be extremely workable not only in helping and rehabbing this type of client in Harlingen, but also in helping them remain abstinent and in a number of situations out of the criminal justice system once and for all.
