Individuals who are physically dependent to drugs or alcohol and want assistance will initially go through detox before receiving other treatment services in drug rehab. Detox is simply the procedure of the drug being removed from one's system, which is often uncomfortable and may hold risks if not executed in a setting which can provide appropriate support and medical intervention as required. Detoxification services are offered at either a professional drug or alcohol detoxification facility or a drug rehabilitation facility which can effectively oversee and provide medical supervision for people who are just coming off of drugs. Detox services often include insuring the client is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and making certain the particular person 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 rehab facility which can present detox services, the individual will have detox staff at their disposal around the clock to make certain that any difficulties are handled as rapidly and safely as possible.
