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. Detox is basically the process of the drug being eradicated from one's system, which is frequently uncomfortable and may hold risks if not executed in a setting which can supply appropriate support and medical intervention as required. Detox services are supplied at either a professional drug or alcohol detox facility or a drug rehab facility which can properly oversee and supply medical supervision for individuals who are just coming off of drugs. Detoxification services usually include insuring the individual is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and making certain the person is receiving proper rest, and supplying supplements and medicine as needed to make the detoxification process as smooth and safe as possible. The individual in detoxification 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 treatment facility which can offer detoxification services, the client will have detox staff at their disposal around the clock to make sure that any difficulties are handled as rapidly and safely as possible.
