Short-term drug rehab and alcohol treatment services in Canterbury are usually delivered in an inpatient or residential setting for a duration of 30 days or less. Though long term drug rehab typically demands 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 rehabilitated through detox followed by a brief course of therapy and counseling to lightly deal with addiction issues. Since it can take several weeks if not months to fully address all issues which may bring about relapse once they go back into the real world, short-term drug rehab and alcohol treatment services may not be adequate for those in Canterbury who have a long termaddiction to drugs and alcohol.
