People who are physically dependent to drugs or alcohol and want assistance will first go through detox before getting other treatment services in drug rehab. Detoxification is simply the procedure of the drug being removed from one's system, which is usually uncomfortable and may hold risks if not conducted in a setting which can provide appropriate support and medical intervention as required. Detox services are supplied at either a professional drug or alcohol detoxification facility or a drug rehab facility which can effectively oversee and supply medical supervision for individuals who are just coming off of drugs. Detoxification services often 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 getting proper rest, and providing supplements and medicine as required to make the detox process as easy and safe as possible. The particular person in detoxification will sometimes be encouraged to take part in some variety of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug treatment facility which can present detoxification services, the person will have detoxification staff at their disposal around the clock to ensure that any complications are resolved as swiftly and safely as possible.
