People who are physically dependent to drugs or alcohol and want help will initially go through detoxification before receiving other treatment services in drug rehab. Detoxification is simply 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 needed. Detoxification services are supplied at either a professional drug or alcohol detoxification facility or a drug rehabilitation facility which can effectively oversee and provide medical supervision for persons who are just coming off of drugs. Detoxification services usually include insuring the client is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and ensuring the individual is receiving proper rest, and supplying supplements and medicine as necessary 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 detox facility or drug rehabilitation facility which can supply detox services, the client will have detox staff at their disposal around the clock to make sure that any difficulties are fixed as quickly and safely as possible.
