Short-term drug rehab and alcohol treatment services in California are typically delivered in a residential or inpatient facility for a period of 30 days or less. While long term drug rehab requires at least a 90 day stay and a lot more rigorous course of treatment, short-term drug rehab and alcohol treatment services work by getting the addicted person rehabilitated through detoxification followed by a brief course of counseling and therapy to lightly deal with addiction issues. Because it usually takes several weeks if not months to completely address all issues which may hang the person up and cause relapse once they go back into the real world, short-term drug rehab and alcohol treatment services may not be recommended for those in California who have a long termdependence and addiction to drugs and alcohol.
