Men and women who are physically reliant to drugs or alcohol and want assistance will 1st go through detoxification before receiving other treatment services in drug rehab. Detoxification is simply the process of the drug being removed 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 needed. Detox services are offered at either a professional drug or alcohol detox facility or a drug rehab facility which can adequately oversee and provide medical supervision for individuals who are just coming off of drugs. Detox services often include insuring the person is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and ensuring the particular person is getting 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 kind of physical activity such as walking, yoga, etc. At a drug detox facility or drug treatment facility which can supply detox services, the person will have detox staff at their disposal around the clock to assure that any problems are fixed as rapidly and safely as possible.
