People who are physically reliant to drugs or alcohol and want help will first 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 typically uncomfortable and may hold risks if not conducted in a setting which can provide appropriate support and medical intervention as necessary. Detox services are provided at either a professional drug or alcohol detoxification facility or a drug rehabilitation facility which can adequately oversee and provide medical supervision for men and women 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, delivering proper nutrition and ensuring the person is receiving proper rest, and providing supplements and medicine as wanted to make the detox process as easy and safe as possible. The individual in detoxification will sometimes be encouraged to take part in some form of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug treatment facility which can supply detox services, the person will have detox staff at their disposal around the clock to make sure that any complications are fixed as rapidly and safely as possible.
