Individuals who are physically reliant to drugs or alcohol and want help will initially go through detox before receiving other treatment services in drug rehab. Detoxification is basically the process of the drug being eliminated from one's system, which is generally uncomfortable and may carry risks if not carried out in a setting which can provide appropriate support and medical intervention as required. Detoxification services are provided at either a professional drug or alcohol detox facility or a drug treatment facility which can effectively oversee and supply medical supervision for people who are just coming off of drugs. Detox services frequently include insuring the client is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and making certain the particular 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 type of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug treatment facility which can offer detox services, the client will have detoxification staff at their disposal around the clock to assure that any difficulties are handled as quickly and safely as possible.
