People who are physically dependent to drugs or alcohol and want help will first go through detoxification before getting other treatment services in drug rehab. Detoxification is simply the process of the drug being removed from one's system, which is typically uncomfortable and may hold risks if not performed in a setting which can offer appropriate support and medical intervention as needed. Detox services are provided at either a professional drug or alcohol detoxification facility or a drug treatment facility which can properly oversee and supply medical supervision for individuals 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, delivering proper nutrition and making certain the person 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 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 detox staff at their disposal around the clock to ensure that any difficulties are fixed as rapidly and safely as possible.
