People who are physically reliant to drugs or alcohol and want assistance will initially go through detoxification before receiving other treatment services in drug rehab. Detoxification is simply the procedure of the drug being removed from one's system, which is frequently uncomfortable and may hold risks if not conducted 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 rehabilitation facility which can appropriately oversee and provide medical supervision for persons who are just coming off of drugs. Detoxification services often include insuring the individual is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and making certain the individual is getting proper rest, and supplying supplements and medicine as needed to make the detoxification process as easy 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 rehab facility which can offer detox services, the individual will have detoxification staff at their disposal around the clock to make sure that any complications are fixed as swiftly and safely as possible.
