People who are physically dependent to drugs or alcohol and want assistance will initially go through detox before getting other treatment services in drug rehab. Detoxification is basically the process of the drug being eradicated from one's system, which is often uncomfortable and may hold risks if not performed in a setting which can supply appropriate support and medical intervention as needed. Detox services are supplied at either a professional drug or alcohol detox facility or a drug rehabilitation facility which can effectively oversee and supply medical supervision for people who are just coming off of drugs. Detox services generally include insuring the client is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and ensuring the particular person is getting proper rest, and providing supplements and medicine as required to make the detoxification process as easy and safe as possible. The individual 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 person will have detoxification staff at their disposal around the clock to make certain that any complications are fixed as rapidly and safely as possible.
