Individuals who are physically dependent to drugs or alcohol and want assistance will first go through detoxification before getting other treatment services in drug rehab. Detox is simply the process of the drug being eliminated from one's system, which is generally uncomfortable and may carry risks if not executed in a setting which can supply appropriate support and medical intervention as needed. Detox services are offered at either a professional drug or alcohol detoxification facility or a drug treatment facility which can adequately oversee and provide medical supervision for people who are just coming off of drugs. Detox services frequently include insuring the individual is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and ensuring the individual is receiving proper rest, and supplying supplements and medicine as required to make the detoxification 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 rehabilitation facility which can present detoxification services, the person will have detoxification staff at their disposal around the clock to make certain that any difficulties are handled as rapidly and safely as possible.
