People who are physically reliant to drugs or alcohol and want assistance will first go through detoxification before receiving other treatment services in drug rehab. Detoxification is simply the process of the drug being removed 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. Detoxification services are provided at either a professional drug or alcohol detox facility or a drug treatment facility which can effectively oversee and supply medical supervision for individuals who are just coming off of drugs. Detox services generally include insuring the person is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and ensuring the particular person is receiving proper rest, and supplying supplements and medicine as required to make the detox process as smooth and safe as possible. The person in detox will sometimes be encouraged to take part in some kind of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug treatment facility which can offer detox services, the person will have detoxification staff at their disposal around the clock to make sure that any complications are resolved as quickly and safely as possible.
