People who are physically dependent to drugs or alcohol and want assistance will first go through detoxification before getting other treatment services in drug rehab. Detoxification is basically the process of the drug being eradicated from one's system, which is usually uncomfortable and may hold risks if not performed in a setting which can supply appropriate support and medical intervention as needed. Detox services are offered at either a professional drug or alcohol detox facility or a drug rehabilitation facility which can properly oversee and provide medical supervision for people who are just coming off of drugs. Detoxification services often include insuring the person is as comfortable 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 needed to make the detoxification process as smooth and safe as possible. The person in detoxification will sometimes be encouraged to take part in some sort of physical activity such as walking, yoga, etc. At a drug detox facility or drug treatment facility which can present detoxification services, the individual will have detox staff at their disposal around the clock to make sure that any complications are fixed as swiftly and safely as possible.
