Individuals who are physically dependent to drugs or alcohol and want help will first go through detox before getting other treatment services in drug rehab. Detoxification is simply the procedure of the drug being eradicated from one's system, which is generally uncomfortable and may hold risks if not carried out in a setting which can supply appropriate support and medical intervention as required. Detox services are provided at either a professional drug or alcohol detox facility or a drug treatment facility which can adequately oversee and supply medical supervision for men and women who are just coming off of drugs. Detox services often include insuring the individual is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and ensuring the individual is getting proper rest, and supplying supplements and medicine as needed to make the detoxification process as smooth and safe as possible. The individual in detox will sometimes be encouraged to take part in some variety of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehab facility which can provide detox services, the client will have detox staff at their disposal around the clock to assure that any difficulties are handled as rapidly and safely as possible.
