Individuals who are physically dependent to drugs or alcohol and want assistance will initially go through detox before receiving other treatment services in drug rehab. Detoxification is simply the procedure of the drug being eliminated from one's system, which is generally uncomfortable and may carry risks if not executed in a setting which can offer appropriate support and medical intervention as necessary. Detox services are offered at either a professional drug or alcohol detox facility or a drug treatment facility which can properly oversee and supply medical supervision for people who are just coming off of drugs. Detoxification 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 particular person is getting proper rest, and providing supplements and medicine as necessary to make the detox 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 rehabilitation facility which can supply detoxification services, the person will have detox staff at their disposal around the clock to ensure that any difficulties are fixed as quickly and safely as possible.
