Short-term drug rehab and alcohol treatment services in Merton are typically delivered in a residential or inpatient setting for a time period of 30 days or less. While long term drug rehab requires at least a 90 day stay and a much more rigorous course of treatment, short-term drug rehab and alcohol treatment services work by getting the individual abstinent through detoxification followed by a short course of counseling and therapy to lightly deal with addiction issues. Since it can take several weeks if not months to completely address everything which could bring about relapse once they go back into the real world, short-term drug rehab and alcohol treatment services may not be recommended for those in Merton who have a long termaddiction to drugs.
