Criminal justice clients in Irwin, Pennsylvania make their way into drug rehabilitation programs 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. Many courts put these types of individuals into the alcohol and drug rehab system because they consider that rehabbing these persons is more productive for the culture at large and for the person, rather than sending them in prison with no rehabilitation at all. This has been established to be very effective not only in helping and rehabilitating this type of client in Irwin, Pennsylvania, but also in helping them remain abstinent and in a lot of instances out of the criminal justice system permanently.
