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