Men and women 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 eliminated from one's system, which is generally uncomfortable and may carry risks if not carried out in a setting which can provide appropriate support and medical intervention as required. Detoxification services are offered at either a professional drug or alcohol detoxification facility or a drug rehab facility which can properly oversee and provide medical supervision for people 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, offering proper nutrition and ensuring the individual is receiving proper rest, and providing supplements and medicine as needed to make the detoxification process as smooth 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 rehabilitation facility which can supply detoxification services, the person will have detoxification staff at their disposal around the clock to assure that any difficulties are fixed as swiftly and safely as possible.
