People who are physically dependent to drugs or alcohol and want assistance will 1st go through detox before receiving other treatment services in drug rehab. Detoxification is basically the process of the drug being removed from one's system, which is generally uncomfortable and may carry risks if not carried out in a setting which can offer appropriate support and medical intervention as required. Detox services are offered at either a professional drug or alcohol detox facility or a drug rehab facility which can effectively oversee and present medical supervision for people who are just coming off of drugs. Detoxification services generally include insuring the person is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and ensuring the person is receiving proper rest, and supplying supplements and medicine as needed to make the detoxification process as smooth and safe as possible. The individual in detox will sometimes be encouraged to take part in some sort of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug treatment facility which can offer detoxification services, the person will have detoxification staff at their disposal around the clock to assure that any complications are handled as rapidly and safely as possible.
