Individuals who are physically dependent to drugs or alcohol and want help will first go through detoxification before receiving other treatment services in drug rehab. Detoxification is simply the process of the drug being eliminated 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 necessary. Detoxification services are provided at either a professional drug or alcohol detoxification facility or a drug rehab facility which can effectively oversee and provide medical supervision for persons who are just coming off of drugs. Detox services usually include insuring the client is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and making certain the person is getting proper rest, and supplying supplements and medicine as necessary to make the detoxification process as easy 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 treatment facility which can present detoxification services, the client will have detoxification staff at their disposal around the clock to make certain that any issues are resolved as rapidly and safely as possible.
