Criminal justice clients in San Francisco make their way into alcohol and drug treatment facilities because they were convicted of crimes relating to drugs, whether they were selling drugs or were in the possession of or high on drugs. Many courts put these types of individuals into the drug and alcohol rehab system mainly due to the fact that they consider that rehabbing them is more helpful for society and for the individual, rather than putting them behind bars with no rehabilitation at all. This has been established to be very successful not only in helping and rehabilitating this type of client in San Francisco, California, but also in keeping them off of drugs and in a number of instances away from the criminal justice system for good.
