Men and women who are physically dependent to drugs or alcohol and want assistance will initially go through detoxification 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 hold risks if not carried out in a setting which can supply appropriate support and medical intervention as needed. Detoxification services are provided at either a professional drug or alcohol detoxification facility or a drug rehab facility which can effectively oversee and provide medical supervision for individuals who are just coming off of drugs. Detoxification services usually include insuring the client is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and making certain the particular 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 detox 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 rehab facility which can supply detoxification services, the person will have detoxification staff at their disposal around the clock to ensure that any problems are handled as quickly and safely as possible.
