People who are physically dependent 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 removed from one's system, which is frequently uncomfortable and may hold risks if not carried out in a setting which can offer appropriate support and medical intervention as necessary. Detoxification services are offered at either a professional drug or alcohol detoxification facility or a drug rehabilitation facility which can properly oversee and provide medical supervision for persons who are just coming off of drugs. Detoxification services typically include insuring the client is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and ensuring the particular person is receiving proper rest, and supplying supplements and medicine as needed to make the detox process as easy and safe as possible. The person in detox will sometimes be encouraged to take part in some variety of physical activity such as walking, yoga, etc. At a drug detox facility or drug treatment facility which can supply detoxification services, the individual will have detoxification staff at their disposal around the clock to assure that any difficulties are resolved as quickly and safely as possible.
