People who are physically dependent to drugs or alcohol and want help will initially go through detoxification before getting other treatment services in drug rehab. Detoxification is simply the process of the drug being eliminated from one's system, which is typically uncomfortable and may carry risks if not conducted 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 properly oversee and provide medical supervision for individuals who are just coming off of drugs. Detox services typically include insuring the individual is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, delivering proper nutrition and ensuring the individual is getting proper rest, and providing supplements and medicine as necessary to make the detox process as smooth and safe as possible. The person in detox will sometimes be encouraged to take part in some type of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehabilitation facility which can offer detox services, the individual will have detox staff at their disposal around the clock to make sure that any complications are handled as rapidly and safely as possible.
