Individuals who are physically dependent to drugs or alcohol and want help will first go through detoxification before receiving other treatment services in drug rehab. Detox is simply the procedure of the drug being eliminated 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 needed. Detox services are provided at either a professional drug or alcohol detoxification facility or a drug treatment facility which can adequately oversee and provide medical supervision for individuals who are just coming off of drugs. Detox services typically include insuring the client is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, delivering proper nutrition and ensuring the particular person is getting proper rest, and providing supplements and medicine as required to make the detox process as smooth and safe as possible. The particular person 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 rehab facility which can offer detoxification services, the client will have detox staff at their disposal around the clock to ensure that any complications are handled as quickly and safely as possible.
