People who are physically dependent to drugs or alcohol and want assistance will first go through detox before getting other treatment services in drug rehab. Detoxification is simply the process of the drug being eradicated from one's system, which is usually uncomfortable and may hold risks if not performed in a setting which can supply appropriate support and medical intervention as required. Detox services are supplied at either a professional drug or alcohol detox facility or a drug rehab facility which can appropriately oversee and supply medical supervision for people who are just coming off of drugs. Detox 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 getting proper rest, and supplying supplements and medicine as wanted to make the detox process as easy and safe as possible. The 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 detoxification services, the client will have detox staff at their disposal around the clock to assure that any problems are fixed as swiftly and safely as possible.
