People who are physically dependent to drugs or alcohol and want assistance will first go through detoxification before getting other treatment services in drug rehab. Detoxification is basically the process of the drug being eradicated 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 needed. Detox services are supplied at either a professional drug or alcohol detoxification facility or a drug treatment facility which can effectively oversee and provide medical supervision for men and women who are just coming off of drugs. Detox services usually include insuring the client is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and ensuring the 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 variety of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehab facility which can supply detox services, the person will have detox staff at their disposal around the clock to make certain that any issues are fixed as rapidly and safely as possible.
