Men and women who are physically dependent to drugs or alcohol and want help will initially go through detoxification before getting other treatment services in drug rehab. Detox is simply the process of the drug being eradicated 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 required. Detoxification services are offered at either a professional drug or alcohol detoxification facility or a drug rehabilitation facility which can adequately oversee and supply medical supervision for men and women who are just coming off of drugs. Detox services typically include insuring the person is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, delivering proper nutrition and making certain the person is receiving proper rest, and providing supplements and medicine as needed to make the detox process as smooth and safe as possible. The person in detoxification will sometimes be encouraged to take part in some sort of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehabilitation facility which can supply detoxification services, the client will have detox staff at their disposal around the clock to assure that any complications are handled as quickly and safely as possible.
