Individuals who are physically dependent to drugs or alcohol and want help will first go through detox before receiving 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 executed in a setting which can supply 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 adequately oversee and present medical supervision for people who are just coming off of drugs. Detox services typically include insuring the client is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, delivering proper nutrition and making certain the person is receiving proper rest, and providing supplements and medicine as necessary to make the detoxification process as smooth 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 detoxification facility or drug rehabilitation facility which can supply detox services, the person will have detox staff at their disposal around the clock to make sure that any issues are fixed as swiftly and safely as possible.
