Individuals who are physically reliant to drugs or alcohol and want help will first go through detox before receiving other treatment services in drug rehab. Detox is simply the process of the drug being eliminated from one's system, which is usually uncomfortable and may hold risks if not executed in a setting which can offer appropriate support and medical intervention as needed. Detoxification services are provided at either a professional drug or alcohol detox facility or a drug rehab facility which can effectively oversee and provide medical supervision for persons who are just coming off of drugs. Detoxification services frequently include insuring the client is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and ensuring the person is receiving proper rest, and providing supplements and medicine as needed to make the detox 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 provide detox services, the person will have detox staff at their disposal around the clock to ensure that any difficulties are fixed as swiftly and safely as possible.
