There are numerous unique types of drug and alcohol abuse rehabilitation services in San Quentin, California which addicted individuals can take advantage of. As an example, there are drug and alcohol abuse rehabilitation services which cater to a treatment client who has a very brief background of drug and alcohol abuse and would potentially find luck at a short term alcohol and drug rehab facility which will call for the individual to reside in rehab for 4 weeks or less. For others there are much more extensive and long term substance abuse rehabilitation services which involve a stay of 90 days or more, depending on the individual's background of drug and alcohol abuse and other things to be considered including co-occurring mental health problems. Drug and alcohol abuse treatment programs in San Quentin can be performed on an outpatient basis or an inpatient basis, with inpatient drug and alcohol abuse treatment programs providing substantially superior results because of a higher quality of rehab setting.
