People who are physically reliant to drugs or alcohol and want help will first go through detoxification before getting other treatment services in drug rehab. Detox is basically the process of the drug being eliminated from one's system, which is generally uncomfortable and may carry risks if not performed in a setting which can supply appropriate support and medical intervention as needed. Detoxification services are supplied at either a professional drug or alcohol detox facility or a drug rehab facility which can adequately oversee and provide medical supervision for people who are just coming off of drugs. Detox services generally include insuring the client is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and making certain the person is receiving proper rest, and supplying supplements and medicine as required 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 detoxification facility or drug treatment facility which can offer detox services, the individual will have detox staff at their disposal around the clock to make sure that any complications are resolved as quickly and safely as possible.
