People who are physically reliant 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 often uncomfortable and may carry risks if not executed in a setting which can offer appropriate support and medical intervention as needed. Detox services are offered at either a professional drug or alcohol detox facility or a drug rehab facility which can properly oversee and provide medical supervision for people who are just coming off of drugs. Detox services typically include insuring the person is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and ensuring the individual is receiving proper rest, and supplying supplements and medicine as needed to make the detox process as smooth and safe as possible. The person in detoxification will sometimes be encouraged to take part in some variety of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug treatment facility which can present detoxification services, the person will have detox staff at their disposal around the clock to guarantee that any difficulties are resolved as swiftly and safely as possible.
