We tested whether snus marketing with modified risk tobacco product (MRTP) claims: (a) promotes accurate knowledge about snus's health effects in young adults and (b) encourages use intentions in only those who use combustible tobacco without attracting other young adult populations.
A randomised between-subjects experiment was embedded in a 2020 web survey of participants from Los Angeles (aged 19-23 years). Participants viewed mass-marketed snus advertising materials with (n=1212) vs without (n=1225) US Food and Drug Administration-authorised MRTP claims. After advertising exposure, snus use intention and perceptions of snus harms relative to cigarettes or e-cigarettes were measured.
Advertisements with versus without MRTP claims did not affect snus use intention (18.0% vs 19.4%) but produced a higher prevalence of perceptions that snus was less harmful than cigarettes (12.6% vs 9.1%; p=0.007) and e-cigarettes (8.0% vs 5.8%; p=0.04). MRTP claim exposure effects did not differ by past 30-day e-cigarette or combustible tobacco use. Snus use intentions after marketing exposure, collapsed across MRTP claim conditions, were higher in those who did versus did not report past 30-day use of e-cigarettes (38.4% vs 14.3%; adjusted OR (95% CI) 2.95 (2.28 to 3.81); p<0.001) or combustible tobacco (44.0% vs 16.2%; adjusted OR (95% CI) 2.26 (1.62 to 3.16); p<0.001).
Although some young adults who vape or smoke may have snus use intentions, snus MRTP claims might not affect young adults' snus use intentions, regardless of whether they vape/smoke. MRTP claims might modestly increase the accuracy of perceived harms of snus relative to cigarettes while also slightly causing unsubstantiated perceptions of lower harm than e-cigarettes.
我们测试了带有改良风险烟草产品（MRTP）声明的鼻烟营销是否：（a）促进了年轻人对鼻烟健康影响的准确认知，以及（b）仅在那些使用可燃烟草的人群中鼓励使用意愿，而不吸引其他年轻人群体。
一项随机组间实验嵌入了2020年对来自洛杉矶（年龄在19 - 23岁）参与者的网络调查中。参与者观看了带有（n = 1212）和不带有（n = 1225）美国食品药品监督管理局批准的MRTP声明的大众市场鼻烟广告材料。在接触广告后，测量了鼻烟使用意愿以及对鼻烟相对于香烟或电子烟危害的认知。
带有与不带有MRTP声明的广告对鼻烟使用意愿没有影响（18.0%对19.4%），但产生了更高比例的认知，即认为鼻烟比香烟危害小（12.6%对9.1%；p = 0.007）以及比电子烟危害小（8.0%对5.8%；p = 0.04）。MRTP声明接触效应在过去30天使用电子烟或可燃烟草的人群中没有差异。在接触营销后，无论MRTP声明情况如何，报告过去30天使用过电子烟的人群的鼻烟使用意愿高于未使用过的人群（38.4%对14.3%；调整后比值比（95%置信区间）2.95（2.28至3.81）；p < 0.001），报告过去30天使用过可燃烟草的人群也是如此（44.0%对16.2%；调整后比值比（95%置信区间）2.26（1.62至3.16）；p < 0.001）。
尽管一些吸电子烟或吸烟的年轻人可能有鼻烟使用意愿，但鼻烟MRTP声明可能不会影响年轻人的鼻烟使用意愿，无论他们是否吸电子烟/吸烟。MRTP声明可能会适度提高对鼻烟相对于香烟危害认知的准确性，同时也会略微导致对鼻烟危害低于电子烟的未经证实的认知。
