Men and women who are physically dependent to drugs or alcohol and want help will initially go through detox before getting other treatment services in drug rehab. Detoxification is basically the procedure of the drug being eliminated from one's system, which is typically uncomfortable and may carry risks if not carried out in a setting which can offer appropriate support and medical intervention as necessary. Detox services are offered at either a professional drug or alcohol detoxification facility or a drug treatment facility which can appropriately oversee and provide medical supervision for people who are just coming off of drugs. Detoxification services generally 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 getting proper rest, and supplying supplements and medicine as required to make the detoxification process as easy and safe as possible. The individual 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 offer detoxification services, the person will have detox staff at their disposal around the clock to make sure that any issues are handled as quickly and safely as possible.
