Individuals who are physically reliant to drugs or alcohol and want help will initially go through detoxification before receiving other treatment services in drug rehab. Detox is simply the procedure of the drug being eradicated from one's system, which is usually uncomfortable and may carry risks if not executed in a setting which can supply appropriate support and medical intervention as necessary. Detoxification services are offered at either a professional drug or alcohol detox facility or a drug rehab facility which can correctly oversee and present medical supervision for persons who are just coming off of drugs. Detox services usually include insuring the individual is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and ensuring the individual is receiving proper rest, and supplying supplements and medicine as wanted to make the detox process as smooth and safe as possible. The person in detox will sometimes be encouraged to take part in some form of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehabilitation facility which can present detox services, the person will have detox staff at their disposal around the clock to ensure that any problems are fixed as quickly and safely as possible.
