People who are physically reliant to drugs or alcohol and want assistance will initially go through detoxification before receiving other treatment services in drug rehab. Detox is basically the procedure of the drug being eliminated from one's system, which is usually uncomfortable and may carry risks if not executed in a setting which can offer appropriate support and medical intervention as required. Detox services are offered at either a professional drug or alcohol detoxification facility or a drug rehabilitation facility which can appropriately oversee and present medical supervision for persons who are just coming off of drugs. Detox services generally include insuring the client is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and ensuring the person is receiving proper rest, and providing supplements and medicine as required to make the detoxification process as easy and safe as possible. The individual in detox will sometimes be encouraged to take part in some type of physical activity such as walking, yoga, etc. At a drug detox facility or drug treatment facility which can present detoxification services, the individual will have detox staff at their disposal around the clock to guarantee that any complications are fixed as swiftly and safely as possible.
