Men and women who are physically reliant to drugs or alcohol and want help will first go through detox before getting other treatment services in drug rehab. Detox is basically the procedure of the drug being eliminated from one's system, which is often uncomfortable and may carry risks if not carried out in a setting which can provide appropriate support and medical intervention as needed. Detoxification services are provided at either a professional drug or alcohol detoxification facility or a drug rehab facility which can correctly oversee and provide medical supervision for people who are just coming off of drugs. Detox services typically include insuring the person is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and ensuring the person is getting proper rest, and providing supplements and medicine as required to make the detox process as easy and safe as possible. The person in detox 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 rehabilitation facility which can present detoxification services, the individual will have detox staff at their disposal around the clock to assure that any issues are fixed as rapidly and safely as possible.
