Men and women who are physically dependent to drugs or alcohol and want assistance will initially go through detoxification before receiving other treatment services in drug rehab. Detoxification is basically the process of the drug being eradicated from one's system, which is usually uncomfortable and may carry risks if not executed in a setting which can supply appropriate support and medical intervention as needed. Detox services are offered at either a professional drug or alcohol detoxification facility or a drug rehabilitation facility which can properly oversee and present medical supervision for persons who are just coming off of drugs. Detoxification services usually include insuring the person is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and making certain the individual is receiving proper rest, and supplying supplements and medicine as required to make the detox process as easy and safe as possible. The individual in detox will sometimes be encouraged to take part in some sort of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug treatment facility which can offer detoxification services, the client will have detox staff at their disposal around the clock to assure that any complications are fixed as swiftly and safely as possible.
