People who are physically dependent to drugs or alcohol and want assistance will first go through detoxification before getting other treatment services in drug rehab. Detox is basically the process of the drug being removed from one's system, which is generally uncomfortable and may carry risks if not conducted in a setting which can provide appropriate support and medical intervention as necessary. Detoxification services are provided at either a professional drug or alcohol detoxification facility or a drug treatment facility which can adequately oversee and provide medical supervision for men and women who are just coming off of drugs. Detoxification services often include insuring the client is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and ensuring the person is receiving proper rest, and supplying supplements and medicine as wanted to make the detox process as easy and safe as possible. The individual in detoxification will sometimes be encouraged to take part in some variety of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehab facility which can provide detoxification services, the client will have detox staff at their disposal around the clock to ensure that any complications are resolved as rapidly and safely as possible.
