Individuals who are physically reliant to drugs or alcohol and want help will first go through detox before receiving other treatment services in drug rehab. Detox is basically the process of the drug being removed from one's system, which is usually uncomfortable and may carry risks if not executed in a setting which can provide appropriate support and medical intervention as required. Detoxification services are supplied at either a professional drug or alcohol detox facility or a drug rehabilitation facility which can correctly oversee and present medical supervision for people 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, supplying proper nutrition and making certain the individual is receiving proper rest, and supplying supplements and medicine as wanted to make the detoxification process as easy and safe as possible. The person in detox will sometimes be encouraged to take part in some sort of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehabilitation facility which can present detox services, the individual will have detox staff at their disposal around the clock to assure that any difficulties are handled as rapidly and safely as possible.
