Quizplus · Accepted Answer

Particulate matter from cigarettes condenses in the lungs to form a thick, brown sludge called tar. Nicotine is the addictive chemical in cigarettes, benzopyrene is a carcinogenic chemical found in cigarette smoke, and phenol is a toxic chemical used in industrial processes that may be present in some types of smoke. However, none of these substances are specifically known for condensing in the lungs to form the thick sludge characteristic of tar.
