Individuals who are physically dependent to drugs or alcohol and want help will first go through detox before getting 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 performed in a setting which can provide appropriate support and medical intervention as needed. Detoxification services are offered at either a professional drug or alcohol detoxification facility or a drug treatment facility which can appropriately oversee and provide medical supervision for people who are just coming off of drugs. Detox services usually include insuring the person is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, delivering proper nutrition and making certain the person is receiving proper rest, and providing supplements and medicine as needed to make the detoxification process as smooth and safe as possible. The particular person 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 rehabilitation facility which can provide detoxification services, the person will have detox staff at their disposal around the clock to ensure that any problems are handled as quickly and safely as possible.
