Individuals who are physically reliant to drugs or alcohol and want help will first go through detox before getting other treatment services in drug rehab. Detox is simply the process of the drug being eliminated from one's system, which is generally uncomfortable and may carry risks if not executed in a setting which can offer appropriate support and medical intervention as needed. Detoxification services are offered at either a professional drug or alcohol detox facility or a drug treatment facility which can adequately oversee and present medical supervision for people who are just coming off of drugs. Detoxification services frequently include insuring the person 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 needed to make the detox process as smooth and safe as possible. The person in detox 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 rehabilitation facility which can present detoxification services, the person will have detox staff at their disposal around the clock to make certain that any difficulties are resolved as swiftly and safely as possible.
