Men and women who are physically reliant to drugs or alcohol and want assistance will first 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 offer appropriate support and medical intervention as necessary. Detox services are supplied at either a professional drug or alcohol detoxification facility or a drug rehab facility which can effectively oversee and present medical supervision for individuals who are just coming off of drugs. Detox services generally include insuring the client is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and ensuring the person is getting proper rest, and providing supplements and medicine as necessary to make the detox process as easy and safe as possible. The person in detox will sometimes be encouraged to take part in some form of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehabilitation facility which can offer detoxification services, the client will have detoxification staff at their disposal around the clock to ensure that any issues are resolved as swiftly and safely as possible.
