People who are physically reliant to drugs or alcohol and want help will first go through detox before getting 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 carried out 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 treatment facility which can effectively oversee and present medical supervision for individuals who are just coming off of drugs. Detoxification services often include insuring the client is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, delivering proper nutrition and ensuring the individual is getting proper rest, and supplying supplements and medicine as needed to make the detoxification process as easy and safe as possible. The person in detoxification will sometimes be encouraged to take part in some sort of physical activity such as walking, yoga, etc. At a drug detox facility or drug treatment facility which can provide detox services, the client will have detox staff at their disposal around the clock to make certain that any complications are resolved as swiftly and safely as possible.
