Individuals who are physically dependent to drugs or alcohol and want assistance will first go through detox before receiving other treatment services in drug rehab. Detox is simply the procedure of the drug being eradicated from one's system, which is typically uncomfortable and may hold risks if not conducted in a setting which can provide appropriate support and medical intervention as needed. Detox services are offered 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. Detox services usually include insuring the client is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, delivering proper nutrition and ensuring the particular person is receiving proper rest, and supplying supplements and medicine as necessary to make the detox process as smooth and safe as possible. The individual in detoxification 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 rehab facility which can offer detoxification services, the person will have detoxification staff at their disposal around the clock to assure that any problems are fixed as quickly and safely as possible.
