People who are physically reliant to drugs or alcohol and want help will first go through detox before receiving other treatment services in drug rehab. Detox is basically the procedure of the drug being eradicated from one's system, which is frequently uncomfortable and may carry risks if not executed in a setting which can offer appropriate support and medical intervention as needed. Detox services are offered at either a professional drug or alcohol detox facility or a drug rehabilitation facility which can adequately oversee and supply medical supervision for persons 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, supplying proper nutrition and making certain the individual is receiving proper rest, and providing supplements and medicine as needed to make the detox 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 detoxification facility or drug rehab facility which can provide detoxification services, the client will have detox staff at their disposal around the clock to make sure that any complications are handled as swiftly and safely as possible.
