People who are physically dependent to drugs or alcohol and want assistance will first go through detox before getting other treatment services in drug rehab. Detox is simply the procedure of the drug being eradicated 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. 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. Detox services typically include insuring the person is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and ensuring the particular person is getting proper rest, and providing supplements and medicine as necessary to make the detox process as easy and safe as possible. The individual in detoxification 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 detoxification services, the individual will have detoxification staff at their disposal around the clock to guarantee that any issues are resolved as rapidly and safely as possible.
