Men and women who are physically reliant to drugs or alcohol and want assistance will first go through detoxification before getting other treatment services in drug rehab. Detoxification is basically the process of the drug being removed from one's system, which is typically uncomfortable and may carry risks if not conducted in a setting which can supply appropriate support and medical intervention as required. Detoxification services are offered at either a professional drug or alcohol detoxification facility or a drug rehabilitation facility which can correctly oversee and supply medical supervision for persons 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, supplying proper nutrition and ensuring the individual is getting proper rest, and supplying supplements and medicine as needed to make the detoxification process as easy and safe as possible. The particular person in detoxification will sometimes be encouraged to take part in some sort of physical activity such as walking, yoga, etc. At a drug detox facility or drug treatment facility which can supply detoxification services, the person will have detoxification staff at their disposal around the clock to assure that any complications are resolved as quickly and safely as possible.
