People who are physically dependent to drugs or alcohol and want help will 1st go through detoxification before getting other treatment services in drug rehab. Detoxification is simply the procedure of the drug being eliminated from one's system, which is frequently uncomfortable and may hold risks if not performed in a setting which can offer appropriate support and medical intervention as required. Detox services are offered at either a professional drug or alcohol detox facility or a drug treatment facility which can appropriately oversee and present medical supervision for people who are just coming off of drugs. Detoxification services typically include insuring the client is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, delivering proper nutrition and ensuring the person is receiving proper rest, and providing supplements and medicine as needed to make the detoxification process as smooth 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 treatment facility which can provide detox services, the person will have detoxification staff at their disposal around the clock to guarantee that any problems are fixed as quickly and safely as possible.
