Individuals who are physically reliant to drugs or alcohol and want help 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 often uncomfortable and may hold risks if not performed in a setting which can provide appropriate support and medical intervention as required. Detoxification services are provided at either a professional drug or alcohol detoxification facility or a drug rehabilitation facility which can appropriately oversee and supply medical supervision for men and women who are just coming off of drugs. Detoxification services typically include insuring the client is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and ensuring the individual 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 detoxification will sometimes be encouraged to take part in some form of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehab facility which can offer detoxification services, the person will have detox staff at their disposal around the clock to ensure that any problems are handled as quickly and safely as possible.
