People who are physically reliant to drugs or alcohol and want help will first go through detoxification before getting other treatment services in drug rehab. Detoxification is basically the procedure of the drug being eradicated from one's system, which is typically uncomfortable and may hold risks if not carried out in a setting which can offer appropriate support and medical intervention as required. Detoxification services are provided at either a professional drug or alcohol detox facility or a drug rehab facility which can adequately oversee and present medical supervision for persons who are just coming off of drugs. Detoxification services usually include insuring the client is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and making certain the individual is receiving proper rest, and supplying supplements and medicine as required to make the detox process as easy and safe as possible. The person in detoxification will sometimes be encouraged to take part in some kind of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehab facility which can offer detoxification services, the person will have detox staff at their disposal around the clock to guarantee that any difficulties are handled as quickly and safely as possible.
