Men and women who are physically reliant to drugs or alcohol and want help will first go through detox before receiving other treatment services in drug rehab. Detox is simply the process 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 supply appropriate support and medical intervention as necessary. Detoxification services are offered at either a professional drug or alcohol detox facility or a drug rehabilitation facility which can adequately oversee and present medical supervision for persons who are just coming off of drugs. Detox services typically include insuring the person is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, delivering proper nutrition and ensuring the person is getting proper rest, and supplying supplements and medicine as required to make the detoxification process as easy and safe as possible. The particular person in detox 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 detox services, the client will have detox staff at their disposal around the clock to ensure that any difficulties are resolved as rapidly and safely as possible.
