nicotine inhaler

(NIH-kuh-TEEN in-HAY-ler)
A device used to inhale (breathe in) small doses of nicotine through the mouth. The nicotine is absorbed through the lining of the mouth and lungs and goes into the blood. This helps stop nicotine cravings and relieves symptoms that occur when a person is trying to quit smoking. A prescription is needed for nicotine inhalers.
