Individuals who are physically reliant to drugs or alcohol and want assistance will first go through detox before receiving other treatment services in drug rehab. Detoxification is basically the process of the drug being eliminated from one's system, which is frequently uncomfortable and may carry risks if not carried out in a setting which can offer appropriate support and medical intervention as necessary. Detox services are supplied at either a professional drug or alcohol detox facility or a drug rehab facility which can adequately oversee and present medical supervision for men and women who are just coming off of drugs. Detox services often include insuring the client is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and ensuring the individual is getting proper rest, and providing supplements and medicine as required to make the detoxification process as smooth 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 detox facility or drug rehab facility which can supply detoxification services, the person will have detoxification staff at their disposal around the clock to make sure that any complications are fixed as swiftly and safely as possible.
