Question

Quizplus · Accepted Answer

Sidestream smoke is the smoke that comes from the burning end of a cigarette, cigar, or pipe. It contains greater concentrations of toxic and carcinogenic compounds than mainstream smoke, which is the smoke exhaled by the smoker. This is because sidestream smoke is not filtered by the cigarette, cigar, or pipe. Nicotine is not mentioned in this statement.

Note: A is false because cigars contain more tobacco than cigarettes and as such, may contain more nicotine in total. However, the nicotine concentration per cigar is usually lower than in cigarettes. B is false because tolerance to nicotine can develop within hours of smoking the first cigarette, although the degree of tolerance may vary among individuals. D is false because the harshness of smoke is not necessarily an indicator of its hazardousness.
