Criminal justice clients in Canadian make their way into drug and alcohol treatment programs because they were found guilty of crimes relating to drugs, whether they were selling drugs or had drugs in their possession or were high on drugs. Many courts put these criminal individuals into the drug treatment system mainly due to the fact that they believe that treating these individuals is more helpful for the culture at large and for the person, rather than sending them behind bars with no treatment at all. This has been established to be incredibly effective not only in helping and rehabilitating this type of client in Canadian, but also in keeping them sober and in a number of instances away from the criminal justice system once and for all.
