People who are physically dependent to drugs or alcohol and want help will first go through detoxification before getting other treatment services in drug rehab. Detox is simply the process of the drug being removed from one's system, which is frequently uncomfortable and may carry risks if not performed in a setting which can provide appropriate support and medical intervention as required. Detoxification services are offered at either a professional drug or alcohol detox facility or a drug rehab facility which can correctly oversee and supply medical supervision for men and women who are just coming off of drugs. Detoxification services usually include insuring the client is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and ensuring the individual is receiving proper rest, and supplying supplements and medicine as needed to make the detoxification process as easy and safe as possible. The individual in detoxification will sometimes be encouraged to take part in some type of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug treatment facility which can offer detox services, the individual will have detoxification staff at their disposal around the clock to assure that any issues are resolved as quickly and safely as possible.
