People who are physically dependent to drugs or alcohol and want help will initially go through detox before getting other treatment services in drug rehab. Detox is simply the procedure of the drug being removed from one's system, which is usually uncomfortable and may hold risks if not performed in a setting which can offer appropriate support and medical intervention as required. Detoxification services are offered at either a professional drug or alcohol detox facility or a drug treatment facility which can appropriately oversee and provide medical supervision for individuals 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, providing 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 person in detox will sometimes be encouraged to take part in some kind of physical activity such as walking, yoga, etc. At a drug detox facility or drug treatment facility which can provide detox services, the person will have detox staff at their disposal around the clock to guarantee that any difficulties are handled as quickly and safely as possible.
