Individuals who are physically dependent to drugs or alcohol and want assistance will first go through detox before getting other treatment services in drug rehab. Detox is simply the process of the drug being eradicated from one's system, which is typically uncomfortable and may hold risks if not carried out in a setting which can provide appropriate support and medical intervention as needed. Detoxification services are supplied at either a professional drug or alcohol detoxification facility or a drug rehab facility which can effectively oversee and supply medical supervision for men and women who are just coming off of drugs. Detoxification services generally include insuring the person is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and ensuring the person is receiving proper rest, and supplying supplements and medicine as necessary to make the detox process as smooth and safe as possible. The individual in detox will sometimes be encouraged to take part in some type 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 sure that any problems are resolved as swiftly and safely as possible.
