When Paul meets his friends for an evening at a smoke-filled bar, he is exposed to secondhand smoke, also known as

Question

Quizplus · Accepted Answer

Sidestream smoke is the smoke that comes from the burning end of a cigarette, cigar, or pipe. When Paul is in a smoke-filled bar, he is exposed not only to the smoke he inhales directly from his own cigarette or cigar, but also to the sidestream smoke from others' smoking. This is what is commonly referred to as secondhand smoke. Negligible smoke implies a minimal amount of smoke, which may not be the case in a smoke-filled bar. Mainstream smoke refers to the smoke exhaled by the smoker, which is not what Paul is exposed to in this scenario. Involuntary smoke is another term for secondhand smoke, but it is not one of the answer choices.
