People who are physically dependent to drugs or alcohol and want help will 1st go through detox before getting other treatment services in drug rehab. Detoxification is simply the process 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 supply appropriate support and medical intervention as required. Detoxification services are provided at either a professional drug or alcohol detoxification facility or a drug rehabilitation facility which can properly oversee and supply medical supervision for people who are just coming off of drugs. Detox services generally include insuring the person is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, delivering proper nutrition and ensuring the individual is getting proper rest, and supplying supplements and medicine as wanted to make the detoxification 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 rehabilitation facility which can provide detoxification services, the person will have detoxification staff at their disposal around the clock to assure that any difficulties are fixed as rapidly and safely as possible.
