Individuals who are physically reliant to drugs or alcohol and want assistance will first go through detoxification before receiving other treatment services in drug rehab. Detoxification is simply the process of the drug being eliminated from one's system, which is usually uncomfortable and may carry risks if not conducted in a setting which can provide appropriate support and medical intervention as necessary. Detox services are supplied at either a professional drug or alcohol detox facility or a drug rehabilitation facility which can appropriately oversee and present medical supervision for individuals who are just coming off of drugs. Detox services generally include insuring the client is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, delivering proper nutrition and ensuring the individual is receiving proper rest, and supplying supplements and medicine as necessary to make the detox process as smooth and safe as possible. The person in detoxification will sometimes be encouraged to take part in some variety of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehab facility which can offer detox services, the person will have detox staff at their disposal around the clock to make certain that any complications are fixed as swiftly and safely as possible.
