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 eradicated from one's system, which is usually uncomfortable and may carry risks if not carried out in a setting which can offer appropriate support and medical intervention as required. Detoxification services are offered at either a professional drug or alcohol detoxification facility or a drug rehabilitation facility which can correctly oversee and provide medical supervision for men and women who are just coming off of drugs. Detox services often include insuring the client is as comfortable 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 wanted to make the detox 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 person will have detoxification staff at their disposal around the clock to make sure that any complications are resolved as swiftly and safely as possible.
