Men and women who are physically dependent to drugs or alcohol and want assistance will initially go through detoxification before getting other treatment services in drug rehab. Detoxification is basically the process of the drug being removed from one's system, which is usually 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 detoxification facility or a drug rehab facility which can effectively oversee and supply medical supervision for individuals who are just coming off of drugs. Detoxification 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 particular person is receiving proper rest, and supplying supplements and medicine as required to make the detoxification process as smooth and safe as possible. The individual in detox will sometimes be encouraged to take part in some form of physical activity such as walking, yoga, etc. At a drug detox facility or drug treatment facility which can supply detoxification services, the individual will have detoxification staff at their disposal around the clock to assure that any issues are handled as swiftly and safely as possible.
