Individuals who are physically reliant to drugs or alcohol and want help will first go through detox before receiving other treatment services in drug rehab. Detox is basically the process of the drug being eradicated from one's system, which is generally uncomfortable and may hold risks if not performed in a setting which can provide appropriate support and medical intervention as necessary. Detox services are offered at either a professional drug or alcohol detoxification facility or a drug rehab facility which can correctly oversee and present medical supervision for persons who are just coming off of drugs. Detoxification services usually include insuring the client is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and ensuring the person is receiving proper rest, and supplying supplements and medicine as needed to make the detox process as easy and safe as possible. The particular person in detox 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 individual will have detoxification staff at their disposal around the clock to make certain that any issues are resolved as swiftly and safely as possible.
