Men and women who are physically dependent to drugs or alcohol and want help will initially go through detoxification before receiving other treatment services in drug rehab. Detox is basically the process of the drug being eradicated from one's system, which is frequently uncomfortable and may carry risks if not executed in a setting which can supply appropriate support and medical intervention as required. Detox services are provided at either a professional drug or alcohol detox facility or a drug rehab facility which can effectively oversee and provide medical supervision for persons who are just coming off of drugs. Detoxification services generally 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 getting proper rest, and supplying supplements and medicine as required to make the detox process as easy and safe as possible. The particular person in detoxification will sometimes be encouraged to take part in some type of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug treatment facility which can present detoxification services, the client will have detox staff at their disposal around the clock to ensure that any complications are handled as swiftly and safely as possible.
