People who are physically dependent to drugs or alcohol and want assistance will initially go through detoxification before getting other treatment services in drug rehab. Detoxification is basically the process of the drug being eliminated from one's system, which is frequently uncomfortable and may hold risks if not executed in a setting which can provide 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 adequately oversee and provide medical supervision for persons who are just coming off of drugs. Detoxification services frequently include insuring the client is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and ensuring the person is receiving proper rest, and providing supplements and medicine as required to make the detoxification process as easy and safe as possible. The individual in detox will sometimes be encouraged to take part in some form of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehabilitation facility which can provide detox 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.
