Men and women who are physically reliant to drugs or alcohol and want help will first go through detoxification before getting 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 carry 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 rehab facility which can adequately oversee and provide medical supervision for persons who are just coming off of drugs. Detoxification services usually include insuring the person is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and ensuring the individual is getting proper rest, and supplying supplements and medicine as needed to make the detox process as easy and safe as possible. The particular person in detoxification will sometimes be encouraged to take part in some kind of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug treatment facility which can supply detoxification services, the individual will have detox staff at their disposal around the clock to ensure that any complications are handled as rapidly and safely as possible.
