Short-term drug rehab and alcohol treatment services in Chelmsford, MA. are ordinarily delivered in a residential or inpatient setting for a time period of 30 days or less. Though long term drug rehabilitation requires at least a 90 day stay and a much more rigorous course of treatment, short-term drug rehab and alcohol treatment services work to get the addicted person abstinent through detox in conjunction with a brief course of counseling and therapy to lightly deal with emotional addiction issues. Because it can take several weeks if not months to completely address all issues which may trigger relapse once they go back into the real world, short-term drug rehab and alcohol treatment services may not be adequate for those in Chelmsford who have a seriousaddiction and/or dependence to drugs.
