Short-term drug rehab and alcohol treatment services in Derry, Pennsylvania are typically delivered in an inpatient or residential facility for a period of 30 days or less. While long term drug rehabilitation 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 individual rehabilitated through detox in conjunction with a brief course of counseling and therapy to lightly address addiction issues. Because it usually takes several weeks if not months to truly address all issues which could trigger relapse once they go back into the real world, short-term drug rehab and alcohol treatment services may not be recommended for those in Derry who have a long termdependence and addiction to drugs.
