People who are physically reliant to drugs or alcohol and want assistance will initially go through detoxification before getting other treatment services in drug rehab. Detoxification is basically the procedure 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 provide appropriate support and medical intervention as required. Detoxification services are supplied at either a professional drug or alcohol detox facility or a drug rehabilitation facility which can effectively oversee and present medical supervision for individuals who are just coming off of drugs. Detox services usually include insuring the person is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and ensuring 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 particular person in detoxification 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 provide detoxification services, the client will have detox staff at their disposal around the clock to make certain that any difficulties are fixed as quickly and safely as possible.
