Men and women who are physically dependent to drugs or alcohol and want assistance will first go through detox before getting other treatment services in drug rehab. Detox is simply the process of the drug being eliminated 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 supplied at either a professional drug or alcohol detox facility or a drug rehabilitation facility which can appropriately oversee and present medical supervision for persons who are just coming off of drugs. Detox services often include insuring the individual is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and ensuring the individual is getting proper rest, and providing supplements and medicine as wanted to make the detox process as smooth and safe as possible. The particular person in detox will sometimes be encouraged to take part in some sort of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehab facility which can provide detox services, the person will have detox staff at their disposal around the clock to assure that any problems are fixed as rapidly and safely as possible.
