People who are physically reliant to drugs or alcohol and want help will initially go through detox before getting other treatment services in drug rehab. Detox is simply the procedure of the drug being removed from one's system, which is generally uncomfortable and may hold risks if not performed in a setting which can supply appropriate support and medical intervention as necessary. Detoxification services are provided at either a professional drug or alcohol detoxification facility or a drug rehab facility which can adequately oversee and provide medical supervision for individuals who are just coming off of drugs. Detoxification services usually include insuring the person is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and ensuring the particular person is receiving proper rest, and supplying supplements and medicine as wanted 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 detoxification facility or drug rehab facility which can present detox services, the person will have detoxification staff at their disposal around the clock to make sure that any difficulties are resolved as swiftly and safely as possible.
