Individuals who are physically dependent to drugs or alcohol and want help will first go through detoxification before receiving other treatment services in drug rehab. Detoxification is basically the procedure of the drug being eradicated from one's system, which is generally uncomfortable and may hold risks if not performed in a setting which can provide appropriate support and medical intervention as required. Detoxification services are offered at either a professional drug or alcohol detoxification facility or a drug treatment facility which can properly oversee and supply medical supervision for individuals who are just coming off of drugs. Detox services often include insuring the person is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and making certain the particular person is receiving proper rest, and supplying supplements and medicine as required to make the detoxification process as easy and safe as possible. The person in detox will sometimes be encouraged to take part in some type of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug treatment facility which can provide detox services, the individual will have detox staff at their disposal around the clock to ensure that any complications are resolved as rapidly and safely as possible.
