Individuals who are physically dependent to drugs or alcohol and want assistance 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 frequently uncomfortable and may hold risks if not executed in a setting which can offer appropriate support and medical intervention as required. Detoxification services are provided at either a professional drug or alcohol detox facility or a drug rehab facility which can appropriately oversee and provide medical supervision for persons who are just coming off of drugs. Detoxification services typically include insuring the client is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and making certain the person is getting proper rest, and providing supplements and medicine as necessary 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 detox facility or drug rehab facility which can offer detox services, the person will have detoxification staff at their disposal around the clock to guarantee that any issues are handled as quickly and safely as possible.
