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