Individuals who are physically dependent to drugs or alcohol and want assistance will first go through detox before receiving other treatment services in drug rehab. Detox is basically the process of the drug being removed from one's system, which is usually uncomfortable and may hold risks if not carried out in a setting which can supply appropriate support and medical intervention as necessary. Detox services are offered at either a professional drug or alcohol detoxification facility or a drug treatment facility which can effectively oversee and present medical supervision for persons who are just coming off of drugs. Detox services typically include insuring the individual is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and ensuring the person is receiving proper rest, and supplying supplements and medicine as needed to make the detox process as smooth and safe as possible. The particular person 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 rehab facility which can offer detoxification services, the individual will have detoxification staff at their disposal around the clock to guarantee that any difficulties are handled as swiftly and safely as possible.
