People who are physically dependent to drugs or alcohol and want assistance will initially go through detox before receiving other treatment services in drug rehab. Detoxification is simply 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 required. Detoxification services are provided at either a professional drug or alcohol detox facility or a drug treatment facility which can properly oversee and provide medical supervision for men and women who are just coming off of drugs. Detoxification services typically include insuring the client is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and ensuring the person is receiving proper rest, and supplying supplements and medicine as necessary to make the detox process as smooth 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 supply detoxification services, the client will have detoxification staff at their disposal around the clock to assure that any complications are fixed as rapidly and safely as possible.
