People who are physically dependent to drugs or alcohol and want assistance will first go through detox before receiving other treatment services in drug rehab. Detoxification is simply the process of the drug being eradicated from one's system, which is generally uncomfortable and may hold risks if not conducted in a setting which can supply appropriate support and medical intervention as needed. Detox services are offered at either a professional drug or alcohol detox facility or a drug treatment facility which can correctly oversee and present medical supervision for people 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 making certain the individual is receiving proper rest, and providing 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 form of physical activity such as walking, yoga, etc. At a drug detox facility or drug treatment facility which can provide detox services, the person will have detox staff at their disposal around the clock to ensure that any issues are resolved as quickly and safely as possible.
