Treating men and women who are addicted to drugs and have ended up in the criminal justice system has proven effective in curbing future drug related criminal offenses for people who do take advantage of treatment programs. For criminal justice clients in Oakland that do agree to take part in treatment in alcohol and drug rehabilitation centers, even if not of their own choice as is sometimes court ordered, these clients have a much better shot of dealing with the root of the problem so that they can remain sober and off of being implicated in drug related criminal activity. The costs to society related to these drug related crimes is also impacted beneficially when criminal justice clients turn out to be rehabbed in drug and alcohol rehab centers in Oakland instead of incarceration or other penalties.
