People who are physically dependent to drugs or alcohol and want help will first 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 generally uncomfortable and may carry risks if not performed in a setting which can supply appropriate support and medical intervention as required. Detoxification services are provided at either a professional drug or alcohol detox facility or a drug treatment facility which can appropriately oversee and supply medical supervision for persons who are just coming off of drugs. Detox services typically include insuring the individual 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 needed to make the detoxification process as easy and safe as possible. The particular person in detox will sometimes be encouraged to take part in some type of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehabilitation facility which can offer detoxification services, the individual will have detox staff at their disposal around the clock to make sure that any issues are fixed as rapidly and safely as possible.
