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. Detoxification is simply the process of the drug being eradicated from one's system, which is typically uncomfortable and may carry risks if not conducted in a setting which can provide appropriate support and medical intervention as necessary. Detoxification services are offered at either a professional drug or alcohol detox facility or a drug rehabilitation facility which can correctly oversee and present medical supervision for individuals who are just coming off of drugs. Detox services typically include insuring the individual is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, delivering proper nutrition and ensuring the person 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 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 rehab facility which can present detox services, the individual will have detoxification staff at their disposal around the clock to make certain that any complications are handled as quickly and safely as possible.
