People who are physically dependent to drugs or alcohol and want assistance will first go through detox before receiving other treatment services in drug rehab. Detoxification is simply the procedure of the drug being eradicated from one's system, which is typically uncomfortable and may hold risks if not performed in a setting which can provide appropriate support and medical intervention as required. Detox services are supplied at either a professional drug or alcohol detoxification facility or a drug rehabilitation facility which can adequately oversee and supply medical supervision for people who are just coming off of drugs. Detox services frequently include insuring the person is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and ensuring the particular person is getting proper rest, and providing supplements and medicine as required to make the detox process as easy 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 detox facility or drug treatment facility which can supply detoxification services, the client will have detoxification staff at their disposal around the clock to ensure that any problems are handled as swiftly and safely as possible.
