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. Detox is simply the procedure of the drug being eliminated from one's system, which is generally uncomfortable and may hold risks if not executed in a setting which can offer appropriate support and medical intervention as required. Detoxification services are provided at either a professional drug or alcohol detox facility or a drug rehab facility which can correctly oversee and supply medical supervision for persons who are just coming off of drugs. Detox services often include insuring the individual is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and ensuring the particular person is receiving proper rest, and providing supplements and medicine as necessary to make the detox process as easy and safe as possible. The person in detoxification will sometimes be encouraged to take part in some form of physical activity such as walking, yoga, etc. At a drug detox facility or drug treatment facility which can supply detoxification services, the individual will have detox staff at their disposal around the clock to ensure that any difficulties are fixed as swiftly and safely as possible.
