- ultra light cigarette
- listen (UL-truh lite SIH-guh-ret)
A type of cigarette that is claimed to give off less tobacco tar than a regular or light (“low-tar”) cigarette when smoked. Ultra light cigarettes have been shown to be no safer than regular cigarettes, and smoking them does not lower the risk of cancer or other diseases. A person smoking an ultra light cigarette can inhale the same amount of tobacco tar, nicotine, and harmful, cancer-causing chemicals as in a regular cigarette, depending on how the cigarette is smoked. Cigarettes are no longer allowed to be labeled or advertised as ultra light cigarettes.
