Individuals who are physically reliant to drugs or alcohol and want assistance will initially go through detoxification before receiving other treatment services in drug rehab. Detox is simply the process of the drug being removed from one's system, which is typically uncomfortable and may carry risks if not performed in a setting which can supply appropriate support and medical intervention as required. Detoxification services are provided at either a professional drug or alcohol detox facility or a drug rehabilitation facility which can effectively oversee and supply medical supervision for men and women who are just coming off of drugs. Detoxification services typically include insuring the individual is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and ensuring the person is getting 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 type of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehabilitation facility which can offer detox services, the individual will have detoxification staff at their disposal around the clock to assure that any difficulties are resolved as swiftly and safely as possible.
