People who are physically reliant to drugs or alcohol and want help will initially go through detox before receiving other treatment services in drug rehab. Detox is basically the procedure of the drug being eliminated from one's system, which is typically uncomfortable and may hold risks if not carried out in a setting which can supply appropriate support and medical intervention as necessary. Detox services are provided at either a professional drug or alcohol detox facility or a drug rehabilitation facility which can adequately oversee and supply medical supervision for men and women who are just coming off of drugs. Detox services generally include insuring the person is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and making certain the person is receiving proper rest, and providing supplements and medicine as necessary to make the detoxification process as easy and safe as possible. The person in detox will sometimes be encouraged to take part in some sort of physical activity such as walking, yoga, etc. At a drug detox facility or drug treatment facility which can present detoxification services, the client will have detox staff at their disposal around the clock to ensure that any problems are handled as quickly and safely as possible.
