People who are physically dependent to drugs or alcohol and want help will first go through detox before receiving other treatment services in drug rehab. Detoxification is simply the process of the drug being eradicated from one's system, which is generally uncomfortable and may carry risks if not executed in a setting which can provide appropriate support and medical intervention as required. Detox services are provided at either a professional drug or alcohol detoxification facility or a drug treatment facility which can appropriately oversee and supply medical supervision for people who are just coming off of drugs. Detox services usually include insuring the client is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and making certain the particular 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 detoxification 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 treatment facility which can supply detoxification services, the client will have detox staff at their disposal around the clock to guarantee that any complications are fixed as swiftly and safely as possible.
