People who are physically reliant to drugs or alcohol and want help will first 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 executed in a setting which can provide appropriate support and medical intervention as needed. Detoxification services are provided at either a professional drug or alcohol detox facility or a drug rehabilitation facility which can effectively oversee and provide medical supervision for people 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 getting proper rest, and supplying supplements and medicine as required to make the detoxification process as easy 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 offer detoxification services, the individual will have detoxification staff at their disposal around the clock to make certain that any problems are handled as swiftly and safely as possible.
