Men and women who are physically reliant to drugs or alcohol and want help will first go through detoxification before getting other treatment services in drug rehab. Detoxification is simply the process of the drug being removed from one's system, which is generally uncomfortable and may carry risks if not conducted in a setting which can offer appropriate support and medical intervention as necessary. Detoxification services are offered at either a professional drug or alcohol detoxification facility or a drug rehab facility which can adequately oversee and supply medical supervision for persons who are just coming off of drugs. Detox services often include insuring the person is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and ensuring the particular person is getting proper rest, and providing supplements and medicine as necessary to make the detoxification process as easy and safe as possible. The person in detox will sometimes be encouraged to take part in some form of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehab facility which can present detoxification services, the person will have detox staff at their disposal around the clock to ensure that any difficulties are fixed as swiftly and safely as possible.
