Short-term drug rehab and alcohol treatment services in Advent are usually delivered in an inpatient or residential facility for a duration of 30 days or less. While long term drug rehabilitation requires at least a 90 day stay and a much more demanding course of treatment, short-term drug rehab and alcohol treatment services work by getting the addicted person abstinent through detoxification followed by a brief course of therapy and counseling to lightly deal with emotional addiction issues. Because it usually takes several weeks if not months to fully address everything which might 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 sufficient for those in Advent who have a long termdependence and addiction to drugs and alcohol.
