Individuals who are physically dependent to drugs or alcohol and want help will initially go through detox before getting other treatment services in drug rehab. Detoxification is simply the process of the drug being eliminated from one's system, which is generally uncomfortable and may hold risks if not performed in a setting which can supply appropriate support and medical intervention as necessary. Detox services are offered at either a professional drug or alcohol detox facility or a drug rehabilitation facility which can properly oversee and present medical supervision for persons who are just coming off of drugs. Detoxification services frequently include insuring the person is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, providing 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 person in detox will sometimes be encouraged to take part in some type of physical activity such as walking, yoga, etc. At a drug detox facility or drug treatment facility which can present detoxification services, the client will have detox staff at their disposal around the clock to make certain that any problems are handled as rapidly and safely as possible.
