Men and women 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 often 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 detoxification facility or a drug treatment facility which can correctly oversee and supply medical supervision for individuals who are just coming off of drugs. Detoxification services often include insuring the individual is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and making certain the individual is receiving proper rest, and supplying supplements and medicine as necessary 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 rehab facility which can supply detoxification services, the individual will have detox staff at their disposal around the clock to ensure that any complications are resolved as quickly and safely as possible.
