Individuals who are physically dependent to drugs or alcohol and want assistance will initially go through detoxification before getting other treatment services in drug rehab. Detoxification is simply the process of the drug being eliminated from one's system, which is usually uncomfortable and may hold risks if not executed in a setting which can provide appropriate support and medical intervention as necessary. Detoxification services are offered at either a professional drug or alcohol detox facility or a drug rehabilitation facility which can correctly oversee and supply medical supervision for men and women who are just coming off of drugs. Detox services often include insuring the client is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and making certain the person is getting proper rest, and supplying supplements and medicine as required to make the detoxification process as smooth and safe as possible. The person 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 detox services, the person will have detoxification staff at their disposal around the clock to ensure that any complications are fixed as rapidly and safely as possible.
