Individuals who are physically reliant to drugs or alcohol and want assistance will first go through detox before receiving other treatment services in drug rehab. Detoxification is simply the process of the drug being eliminated from one's system, which is often uncomfortable and may hold 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 detoxification facility or a drug rehabilitation facility which can adequately oversee and provide medical supervision for people who are just coming off of drugs. Detox services frequently include insuring the individual is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and ensuring the person is getting proper rest, and supplying 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 form of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug treatment facility which can supply detoxification services, the person will have detoxification staff at their disposal around the clock to make sure that any complications are fixed as swiftly and safely as possible.
