Men and women who are physically reliant to drugs or alcohol and want assistance will first go through detox before getting other treatment services in drug rehab. Detox is basically the process of the drug being eliminated from one's system, which is frequently uncomfortable and may hold risks if not performed in a setting which can supply appropriate support and medical intervention as necessary. Detoxification services are supplied at either a professional drug or alcohol detoxification facility or a drug rehabilitation facility which can adequately oversee and provide medical supervision for persons who are just coming off of drugs. Detox services generally 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 required to make the detoxification process as smooth and safe as possible. The individual in detox will sometimes be encouraged to take part in some kind of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehab facility which can present detoxification services, the individual will have detox staff at their disposal around the clock to make certain that any problems are resolved as swiftly and safely as possible.
