Quizplus · Accepted Answer

Sidestream smoke is the smoke that comes from the burning end of a cigarette, cigar, or pipe. Mainstream smoke is the smoke that is exhaled by a smoker. Since sidestream smoke is not filtered by the cigarette and is cooler, it contains higher levels of unburned particles such as tar, carbon monoxide, and other harmful chemicals than mainstream smoke.
