Nonsmokers and smokers were compared for olfactory sensitivity to two odors associated with cigarettes: nicotine and menthol. Smokers were tested twice--while nonabstinent, and after 16-20 h of smoking abstinence. Smokers showed a higher olfactory threshold for nicotine than did nonsmokers, but the same threshold for menthol. Furthermore, when the smokers were abstinent, they showed a lower olfactory threshold for nicotine than when they were nonabstinent, but again, the same threshold for menthol. These results suggest a nicotine specific olfactory deficit in smokers that is reduced during abstinence.
研究人员比较了非吸烟者和吸烟者对两种与香烟相关气味(尼古丁和薄荷醇)的嗅觉敏感度。吸烟者接受了两次测试——一次是在未戒烟时,另一次是在戒烟16 - 20小时后。吸烟者对尼古丁的嗅觉阈值高于非吸烟者,但对薄荷醇的阈值相同。此外,当吸烟者处于戒烟状态时,他们对尼古丁的嗅觉阈值比未戒烟时低,但对薄荷醇的阈值仍然相同。这些结果表明吸烟者存在尼古丁特异性嗅觉缺陷,而这种缺陷在戒烟期间会有所减轻。
