People who are physically dependent to drugs or alcohol and want assistance will initially go through detox before getting other treatment services in drug rehab. Detox is basically the process of the drug being eliminated from one's system, which is frequently uncomfortable and may hold risks if not carried out in a setting which can provide 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 properly oversee and provide medical supervision for people who are just coming off of drugs. Detoxification services usually include insuring the client is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and ensuring the particular 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 type of physical activity such as walking, yoga, etc. At a drug detox facility or drug treatment facility which can supply detoxification services, the individual will have detox staff at their disposal around the clock to guarantee that any difficulties are handled as swiftly and safely as possible.
