People who are physically reliant to drugs or alcohol and want help will first go through detox before getting other treatment services in drug rehab. Detoxification is basically the procedure of the drug being eliminated from one's system, which is usually uncomfortable and may hold risks if not conducted in a setting which can offer appropriate support and medical intervention as needed. Detoxification services are supplied at either a professional drug or alcohol detoxification facility or a drug rehab facility which can adequately oversee and present medical supervision for persons who are just coming off of drugs. Detoxification services frequently 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 getting proper rest, and providing supplements and medicine as required to make the detox process as smooth and safe as possible. The individual in detox will sometimes be encouraged to take part in some sort of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug treatment facility which can present detoxification services, the person will have detox staff at their disposal around the clock to make sure that any problems are resolved as swiftly and safely as possible.
