People 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 simply the process of the drug being eradicated from one's system, which is frequently uncomfortable and may hold risks if not conducted in a setting which can supply appropriate support and medical intervention as needed. Detoxification services are offered at either a professional drug or alcohol detox facility or a drug rehab facility which can appropriately oversee and supply medical supervision for persons who are just coming off of drugs. Detoxification services typically include insuring the person is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, supplying 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 individual in detoxification will sometimes be encouraged to take part in some kind of physical activity such as walking, yoga, etc. At a drug detox facility or drug treatment facility which can supply detoxification services, the client will have detoxification staff at their disposal around the clock to ensure that any difficulties are resolved as swiftly and safely as possible.
