Men and women who are physically reliant to drugs or alcohol and want help will first go through detoxification before receiving other treatment services in drug rehab. Detoxification is basically the process of the drug being removed from one's system, which is generally uncomfortable and may carry risks if not performed in a setting which can provide appropriate support and medical intervention as required. Detox services are supplied at either a professional drug or alcohol detoxification facility or a drug rehabilitation facility which can adequately oversee and provide medical supervision for men and women who are just coming off of drugs. Detox services generally include insuring the client is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and ensuring the particular person is getting proper rest, and supplying supplements and medicine as required to make the detox process as easy and safe as possible. The person in detox will sometimes be encouraged to take part in some type of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehab facility which can supply detoxification services, the client will have detox staff at their disposal around the clock to guarantee that any difficulties are handled as quickly and safely as possible.
