People who are physically dependent to drugs or alcohol and want help will first go through detox 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 carried out in a setting which can supply appropriate support and medical intervention as needed. Detoxification services are supplied at either a professional drug or alcohol detox facility or a drug rehabilitation facility which can adequately oversee and supply medical supervision for people who are just coming off of drugs. Detoxification services usually include insuring the individual is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and ensuring the individual is receiving proper rest, and providing supplements and medicine as wanted to make the detoxification process as smooth and safe as possible. The person in detox will sometimes be encouraged to take part in some kind of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehab facility which can provide detox services, the individual will have detox staff at their disposal around the clock to ensure that any complications are handled as swiftly and safely as possible.
