Residential long-term treatment is a kind of drug rehabilitation program which provides rehab services for over 30 days. At a residential long-term drug rehab facility the treatment client will either be detoxed prior to arriving at the facility or be seen through detox and withdrawal at the program itself. Drug rehab professionals will then work intensively with the treatment client to handle deep rooted drug addiction problems through counseling and other other treatment methods. This not only helps get them in Derry off of drugs but will help them remain abstinent by resolving the real reasons they abused drugs in the first place. Because this process may require weeks or months in treatment, a residential long-term rehab facility which requires a stay of more than 30 days is a superior choice in terms of alcohol and drug rehabilitation available in Derry and an option which ensures the most significant long term results when looking at success rates.
