Individuals who are physically dependent to drugs or alcohol and want assistance will initially go through detox before receiving other treatment services in drug rehab. Detoxification is simply the procedure of the drug being removed from one's system, which is often uncomfortable and may hold risks if not executed in a setting which can offer appropriate support and medical intervention as needed. Detox services are supplied at either a professional drug or alcohol detoxification facility or a drug rehab facility which can appropriately oversee and supply medical supervision for men and women who are just coming off of drugs. Detoxification services usually include insuring the individual is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, delivering proper nutrition and ensuring the person is receiving proper rest, and supplying supplements and medicine as needed to make the detox process as smooth and safe as possible. The individual in detox will sometimes be encouraged to take part in some sort of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehab facility which can provide detoxification services, the client will have detoxification staff at their disposal around the clock to assure that any difficulties are fixed as rapidly and safely as possible.
