People who are physically dependent to drugs or alcohol and want help will first go through detox before getting other treatment services in drug rehab. Detox is basically the procedure of the drug being removed from one's system, which is generally uncomfortable and may carry risks if not executed in a setting which can provide 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 adequately oversee and supply medical supervision for individuals who are just coming off of drugs. Detox services usually include insuring the person is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and making certain the person is receiving proper rest, and supplying supplements and medicine as necessary to make the detoxification process as easy and safe as possible. The individual in detox will sometimes be encouraged to take part in some variety of physical activity such as walking, yoga, etc. At a drug detox facility or drug treatment facility which can supply detoxification services, the person will have detox staff at their disposal around the clock to make sure that any complications are fixed as swiftly and safely as possible.
