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 process of the drug being removed from one's system, which is often uncomfortable and may hold risks if not conducted in a setting which can supply appropriate support and medical intervention as needed. Detox services are provided at either a professional drug or alcohol detox facility or a drug treatment facility which can properly oversee and supply medical supervision for men and women who are just coming off of drugs. Detoxification services typically include insuring the client is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and making certain the person is getting proper rest, and providing supplements and medicine as required to make the detoxification process as smooth and safe as possible. The person in detox will sometimes be encouraged to take part in some form of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehabilitation facility which can supply detoxification services, the person will have detox staff at their disposal around the clock to guarantee that any problems are resolved as quickly and safely as possible.
