The medical and scientific name for secondhand smoke is

• A. passive smoke
• B. bystander smoke
• C. secondary smoke
• D. limited smoke

Answer: (A)

The key idea is the medical terminology used for what non-smokers inhale from tobacco use. Secondhand smoke is described as passive smoke, capturing the notion that people are exposed to tobacco smoke without actively smoking themselves. This term emphasizes exposure to smoke from others or from burning tobacco rather than the act of smoking. Other phrases like bystander smoke, secondary smoke, or limited smoke aren’t standard medical terms, which is why the best answer is passive smoke. You’ll also see the formal term environmental tobacco smoke used in research and public health literature to describe the same exposure.
