Individuals who are physically reliant to drugs or alcohol and want help will initially go through detox before receiving other treatment services in drug rehab. Detox is simply the process of the drug being removed from one's system, which is generally uncomfortable and may carry risks if not executed in a setting which can supply appropriate support and medical intervention as required. Detox services are offered at either a professional drug or alcohol detoxification facility or a drug treatment facility which can adequately oversee and supply medical supervision for individuals who are just coming off of drugs. Detox services typically 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 providing supplements and medicine as necessary to make the detoxification process as easy and safe as possible. The person in detoxification will sometimes be encouraged to take part in some kind of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug treatment facility which can supply detoxification services, the individual will have detox staff at their disposal around the clock to make sure that any problems are resolved as rapidly and safely as possible.
