Perceiving the Risks of Low-Yield Ventilated-Filter Cigarettes: The Problem of Hole-Blocking

Part of the Advances in Risk Analysis book series (AIRA, volume 1)


Some smokers of low-yield cigarettes derive higher levels of ‘tar’, nicotine, and carbon monoxide (CO) than advertising or government smoking-machine assays have led them to believe [1–3]. My colleagues and I [4, 5] have been concerned about a specific technique of compensatory smoking — hole-blocking of ventilated filters — that appears to occur with alarming frequency. Ventilation holes in the filter cause each puff of smoke to be diluted with air. In a sample of 39 observed users of ventilated-filter cigarettes, 44% were found to block the ventilation-holes (with their lips or fingers) and hence defeat one of the major strategies that cigarette manufacturers have employed to produce low-yield cigarettes [5].
