Individuals 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 basically the procedure of the drug being removed from one's system, which is often uncomfortable and may carry risks if not performed in a setting which can supply appropriate support and medical intervention as needed. Detox services are provided at either a professional drug or alcohol detoxification facility or a drug treatment facility which can adequately oversee and supply medical supervision for individuals who are just coming off of drugs. Detoxification services generally include insuring the individual is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, delivering proper nutrition and ensuring the particular person is getting proper rest, and providing supplements and medicine as needed to make the detox process as easy and safe as possible. The person in detox will sometimes be encouraged to take part in some form of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehabilitation facility which can provide detoxification services, the client will have detox staff at their disposal around the clock to ensure that any difficulties are handled as swiftly and safely as possible.
