Men and women 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 typically uncomfortable and may carry risks if not executed in a setting which can supply appropriate support and medical intervention as needed. Detox services are provided at either a professional drug or alcohol detoxification facility or a drug rehabilitation facility which can properly oversee and provide medical supervision for individuals who are just coming off of drugs. Detox services usually include insuring the person is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and ensuring the individual is getting proper rest, and supplying supplements and medicine as necessary to make the detox process as smooth and safe as possible. The individual in detoxification 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 treatment facility which can present detox services, the individual will have detox staff at their disposal around the clock to assure that any complications are fixed as quickly and safely as possible.
