People who are physically reliant to drugs or alcohol and want help will initially 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 usually 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 offered at either a professional drug or alcohol detoxification facility or a drug rehab facility which can properly oversee and provide medical supervision for men and women who are just coming off of drugs. Detox services often include insuring the client is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and making certain the person is getting proper rest, and supplying supplements and medicine as necessary to make the detoxification process as easy and safe as possible. The individual 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 rehabilitation facility which can offer detoxification services, the client will have detox staff at their disposal around the clock to make sure that any issues are resolved as swiftly and safely as possible.
