People who are physically reliant to drugs or alcohol and want help will initially go through detoxification before receiving other treatment services in drug rehab. Detox is simply the procedure of the drug being removed from one's system, which is frequently uncomfortable and may hold risks if not performed in a setting which can offer 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 appropriately oversee and provide medical supervision for people who are just coming off of drugs. Detox services frequently include insuring the client 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 supplying supplements and medicine as needed to make the detoxification process as easy and safe as possible. The person in detoxification will sometimes be encouraged to take part in some type of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug treatment facility which can offer detox services, the individual will have detox staff at their disposal around the clock to make sure that any difficulties are handled as swiftly and safely as possible.
