Individuals who are physically reliant to drugs or alcohol and want assistance will initially go through detox before getting other treatment services in drug rehab. Detox is simply the process of the drug being eliminated from one's system, which is typically uncomfortable and may hold risks if not executed in a setting which can supply appropriate support and medical intervention as required. Detox services are offered at either a professional drug or alcohol detox facility or a drug rehabilitation facility which can effectively oversee and provide medical supervision for persons who are just coming off of drugs. Detox services often include insuring the client is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, providing 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 individual in detoxification will sometimes be encouraged to take part in some type of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehab facility which can supply detoxification services, the individual will have detox staff at their disposal around the clock to assure that any issues are resolved as swiftly and safely as possible.
