Individuals who are physically reliant to drugs or alcohol and want help will initially go through detoxification before receiving other treatment services in drug rehab. Detox is simply the process of the drug being removed from one's system, which is frequently uncomfortable and may carry risks if not performed in a setting which can offer appropriate support and medical intervention as necessary. Detox services are offered at either a professional drug or alcohol detoxification facility or a drug rehab facility which can properly oversee and supply medical supervision for individuals who are just coming off of drugs. Detox services frequently include insuring the individual is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and making certain the individual is getting proper rest, and providing supplements and medicine as needed to make the detox process as easy and safe as possible. The person in detoxification will sometimes be encouraged to take part in some type of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehab facility which can offer detox services, the person will have detoxification staff at their disposal around the clock to ensure that any problems are fixed as rapidly and safely as possible.
