People who are physically reliant to drugs or alcohol and want help will first go through detox before receiving other treatment services in drug rehab. Detox is simply the procedure of the drug being eradicated from one's system, which is typically uncomfortable and may hold risks if not executed in a setting which can provide appropriate support and medical intervention as required. Detoxification services are offered at either a professional drug or alcohol detoxification facility or a drug treatment facility which can adequately oversee and supply medical supervision for individuals who are just coming off of drugs. Detoxification services typically include insuring the individual is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, delivering proper nutrition and ensuring the person is getting proper rest, and providing supplements and medicine as necessary to make the detoxification process as easy and safe as possible. The particular person in detox will sometimes be encouraged to take part in some variety of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehab facility which can offer detox services, the individual will have detoxification staff at their disposal around the clock to ensure that any issues are fixed as quickly and safely as possible.
