Men and women who are physically reliant to drugs or alcohol and want assistance will first go through detoxification before receiving other treatment services in drug rehab. Detoxification is basically the procedure of the drug being eradicated from one's system, which is often uncomfortable and may hold risks if not performed in a setting which can offer appropriate support and medical intervention as needed. Detox services are supplied at either a professional drug or alcohol detoxification facility or a drug rehabilitation facility which can effectively oversee and provide medical supervision for persons who are just coming off of drugs. Detox services typically include insuring the person is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, delivering proper nutrition and making certain the individual is receiving proper rest, and providing supplements and medicine as needed to make the detoxification process as smooth and safe as possible. The individual in detoxification will sometimes be encouraged to take part in some kind of physical activity such as walking, yoga, etc. At a drug detox facility or drug treatment facility which can offer detox services, the individual will have detoxification staff at their disposal around the clock to ensure that any problems are resolved as quickly and safely as possible.
