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 usually uncomfortable and may carry risks if not conducted in a setting which can supply appropriate support and medical intervention as required. Detox services are offered at either a professional drug or alcohol detox facility or a drug treatment facility which can effectively oversee and supply medical supervision for individuals who are just coming off of drugs. Detox services generally include insuring the person is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, delivering proper nutrition and ensuring the particular person is getting proper rest, and supplying supplements and medicine as required to make the detoxification process as easy and safe as possible. The individual in detoxification 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 treatment facility which can supply detox services, the individual will have detoxification staff at their disposal around the clock to assure that any difficulties are resolved as rapidly and safely as possible.
