Men and women 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 simply the process of the drug being eliminated from one's system, which is often uncomfortable and may carry risks if not executed in a setting which can supply appropriate support and medical intervention as needed. Detoxification services are provided at either a professional drug or alcohol detoxification facility or a drug treatment facility which can correctly oversee and present medical supervision for persons 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, supplying proper nutrition and ensuring the person is getting proper rest, and supplying supplements and medicine as needed to make the detoxification process as easy and safe as possible. The individual in detoxification will sometimes be encouraged to take part in some sort of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehab facility which can offer detox services, the person will have detox staff at their disposal around the clock to make certain that any difficulties are fixed as swiftly and safely as possible.
