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. Detox is simply the procedure of the drug being removed from one's system, which is usually uncomfortable and may carry risks if not performed in a setting which can offer appropriate support and medical intervention as needed. Detoxification services are supplied at either a professional drug or alcohol detox facility or a drug rehab facility which can correctly oversee and provide medical supervision for people who are just coming off of drugs. Detoxification services frequently include insuring the individual is as comfortable 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 easy and safe as possible. The individual in detoxification will sometimes be encouraged to take part in some type of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehabilitation facility which can offer detox services, the person will have detoxification staff at their disposal around the clock to ensure that any complications are fixed as quickly and safely as possible.
