Individuals who are physically reliant to drugs or alcohol and want assistance will first go through detox before receiving other treatment services in drug rehab. Detox is simply the procedure 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 required. Detoxification services are supplied at either a professional drug or alcohol detoxification facility or a drug rehab facility which can correctly oversee and present medical supervision for men and women 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, providing proper nutrition and making certain the person 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 sort of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehabilitation facility which can offer detox services, the individual will have detoxification staff at their disposal around the clock to ensure that any difficulties are handled as quickly and safely as possible.
