Men and women who are physically reliant to drugs or alcohol and want help will first go through detoxification before getting other treatment services in drug rehab. Detoxification is simply the process of the drug being removed from one's system, which is typically uncomfortable and may hold risks if not executed in a setting which can provide appropriate support and medical intervention as needed. Detox services are offered at either a professional drug or alcohol detoxification facility or a drug treatment facility which can adequately oversee and present medical supervision for individuals who are just coming off of drugs. Detox services often include insuring the individual is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and ensuring the individual is receiving proper rest, and providing supplements and medicine as required to make the detoxification process as smooth and safe as possible. The person in detoxification will sometimes be encouraged to take part in some variety of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehabilitation facility which can present detox services, the individual will have detox staff at their disposal around the clock to assure that any complications are handled as quickly and safely as possible.
