重要性：公众错误地认为极低尼古丁含量（VLNC）香烟比目前的香烟致癌性低，这种信念与VLNC标准下戒烟的动机较低有关。我们研究了VLNC香烟中尼古丁水平的不同描述如何影响公众对尼古丁含量，成瘾性和癌症风险的看法的准确性。方法：参与者是一个全国性的便利样本1353美国成年人（22%吸烟者）。在一项在线实验中，我们将参与者随机分配到VLNC描述中，使用（1）简洁的语言;（2）百分比;（3）解释;（4）百分比和解释;（5）百分比和象形图;或（6）百分比，解释和象形图;或使用（7）FDA的“最小或非成瘾”措辞进行对照描述。结果：与对照组相比，百分比描述导致对尼古丁含量（76%对49%的准确性）和成瘾性（44%对34%）的更准确的感知，但对癌症风险的感知不太准确（56%对68%;所有P
Significance: The public incorrectly believes very low nicotine content (VLNC) cigarettes are less carcinogenic than current cigarettes, a belief associated with lower motivation to quit under a VLNC standard. We examined how different descriptions of the nicotine level in VLNC cigarettes affect the accuracy of the public's perceptions about nicotine content, addictiveness, and cancer risk.Methods: Participants were a national convenience sample of 1353 US adults (22% smokers). In an online experiment, we randomized participants to a VLNC description using (1) concise language; (2) a percentage; (3) an interpretation; (4) a percentage and interpretation; (5) a percentage and a pictograph; or (6) a percentage, interpretation, and pictograph; or to a control description using (7) FDA's "minimally or nonaddictive" phrasing. We assessed accuracy of perceived nicotine content, addictiveness, and cancer risk compared to current cigarettes.Results: Compared to control, the percentage description resulted in more accurate perceptions about nicotine content (76% vs. 49% accuracy) and addictiveness (44% vs. 34%), but less accurate perceptions about cancer risk (56% vs. 68%; all ps
