People who are physically reliant to drugs or alcohol and want assistance will first go through detoxification before getting other treatment services in drug rehab. Detox is basically the process of the drug being eliminated from one's system, which is usually uncomfortable and may carry risks if not carried out in a setting which can provide appropriate support and medical intervention as necessary. Detoxification services are supplied at either a professional drug or alcohol detox facility or a drug rehabilitation facility which can effectively oversee and present medical supervision for men and women who are just coming off of drugs. Detoxification services typically include insuring the client is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, delivering proper nutrition and making certain the person is getting proper rest, and providing supplements and medicine as necessary to make the detoxification process as easy and safe as possible. The individual in detox will sometimes be encouraged to take part in some variety of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehab facility which can provide detox services, the individual will have detoxification staff at their disposal around the clock to make sure that any complications are fixed as quickly and safely as possible.
