Effects of FDA Authorized Smokeless Tobacco Claims Among US Adults Who Smoke Cigarettes

February 11, 2026 updated by: Olivia A. Wackowski, PhD, MPH, Rutgers, The State University of New Jersey
This study will be an online survey experiment conducted with adults who smoke cigarettes (ages 21+) to examine their reactions to modified risk advertising claims authorized by the Food & Drug Administration (FDA) for two smokeless tobacco brands (General Snus and Copenhagen), which describe the lower risks of these products compared to cigarette smoking. The study will compare effects of ads with different two different claim types (i.e. claims about reduced lung cancer risk and claims about reduced risks for multiple disease) versus ads with no reduced-risk claims, and examine effects on message and product perceptions, and interest in using the smokeless tobacco products. This study will also examine how smokers' reactions/interest may vary based on the product brand, and asses prior awareness/exposure to the authorized claims.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
General Relative Harm Perception
Time Frame: Assessed in survey measures completed immediately after viewing the study stimuli
Single item measure asking participants how harmful they think daily use of the viewed smokeless tobacco product would be to their health compared to daily cigarette smoking, (1=a lot less harmful, 2=somewhat less harmful, 3=about the same, 4=somewhat more harmful, 5=a lot more harmful). Higher scores mean thinking the viewed smokeless tobacco product is more harmful than cigarettes.
Assessed in survey measures completed immediately after viewing the study stimuli
Perceptions of Perceived Relative Risks of Diseases
Time Frame: Assessed in survey measures completed immediately after viewing the study stimuli
Assessment of perceived risks of getting various smoking related diseases from using the viewed smokeless tobacco product versus from smoking cigarettes. Responses to 6 parallel questions (each asking about a different disease) were averaged together in this composite item. The question stated: "If you used only [General Snus/Copenhagen - inserted based on brand condition] or only cigarettes every day, which product would make it more likely that you would get": 1) lung cancer; 2) heart disease; 3) mouth cancer; 4) stroke; 5) chronic bronchitis; 6) emphysema. Response options to each were on a 5 point scale from (1=much more likely with General Snus/Copenhagen to 5=much more likely with cigarettes). Results presented here are based on the averages responses to the six items. Higher scores mean thinking risks are greater from smoking cigarettes than from using the viewed smokeless tobacco product.
Assessed in survey measures completed immediately after viewing the study stimuli
Absolute Harm Perception
Time Frame: Assessed in survey measures completed immediately after viewing the study stimuli
Single item measure asking participants how likely or unlikely they think the viewed smokeless tobacco product would be to cause serious health problems during their lifetime, if they used it every day (from 1=not at all likely to 5=extremely likely). Higher scores mean greater likelihood of thinking the product is harmful to health.
Assessed in survey measures completed immediately after viewing the study stimuli
Product Use Intentions
Time Frame: Assessed in survey measures completed immediately after viewing the study stimuli
Assessment of intentions to use the viewed smokeless tobacco products based on averaging responses to three parallel questions: "Thinking about the ads you saw for [General Snus or Copenhagen] products, how interested, in the next 6 months, would you be in: 1) Using or trying these products? 2) Using these products as a way to quit or cut down on your cigarette smoking? 3) Completely switching from cigarettes to these products? Response options to each were on a 5 point scale from (1=not at all interested to 5=extremely interested). Results presented here are based on the averaged responses to these three items. Higher scores mean greater interest in using the products.

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Risk Message Recall
Time Frame: Assessed in survey measures completed immediately after viewing the study stimuli
Participants are asked to recall (yes/no) if the ads they viewed include any statement saying that using the product can lower risks of certain diseases.
Assessed in survey measures completed immediately after viewing the study stimuli
Ad Persuasiveness
Time Frame: Assessed in survey measures completed immediately after viewing the study stimuli
A composite measure based on the average of 6 advertisement perceptions, asking participants to rate whether they agreed or disagreed that they ads they viewed: 1) included important information; 2) were understandable; 3) included believable information; 4) included credible information; 5) included information new to me; 6) make me want to learn more about those products. Response options were on a 6 point agreement scale from 1=strongly disagree to 6=strongly agree. Higher scores mean greater agreement that the ads were effective and persuasive.
Assessed in survey measures completed immediately after viewing the study stimuli
Claim Believability & Credibility
Time Frame: Assessed in survey measures completed immediately after viewing the study stimuli
A composite measure based on the average of 2 claim perception items, asking participants to rate whether they agreed or disagreed that the modified-risk claim in the ads they viewed was : 1) believable 2) credible. Participants responded to this while seeing the claim again on the survey screen. Response options were on a 7 point agreement scale from 1=strongly disagree to 7=strongly agree. Higher scores mean greater agreement that the claims were believable and credible.
Assessed in survey measures completed immediately after viewing the study stimuli
Overall Perceived Claim Persuasiveness
Time Frame: Assessed in survey measures completed immediately after viewing the study stimuli
A composite measure based on the average of 7 claim perception items, asking participants to rate whether they agreed or disagreed that the modified-risk claim in the ads they viewed was : 1) believable; 2) credible; 3) important; 4) new to me; 5) makes me think using this product could be less harmful to my health than smoking; 6) makes me more interested in trying this product; 7) would make me think seriously about completely switching to this product. Participants responded to this while seeing the claim again on the survey screen. Response options were on a 7 point agreement scale from 1=strongly disagree to 7=strongly agree. Higher scores mean greater agreement that participants thought the claim was persuasive/effective.
Assessed in survey measures completed immediately after viewing the study stimuli
Switching Comprehension
Time Frame: Assessed in survey measures completed immediately after viewing the study stimuli

An item assessing participants' understanding of the need to completely switch to the smokeless tobacco product viewed in order to reduce risks. It said:

Please answer the next question based on your understanding of the ads you viewed earlier. Based on the ads, [General Snus OR Copenhagen, inserted based on condition] can reduce a smoker's health risks if you: (Select all that apply)

  1. Use only [General Snus/Copenhagen] and not smoke any cigarettes anymore
  2. Use [General Snus/Copenhagen] and smoke fewer cigarettes than before
  3. Use both products ([General Snus/Copenhagen] and cigarettes) about equally
  4. None of the above
  5. I don't know/not sure

Plan for Individual participant data (IPD)

Plan to Share Individual Participant Data (IPD)?

YES

IPD Plan Description

The study ad stimuli, survey instrument, codebook, and de-identified dataset will be deposited to a data repository - we anticipate this will be the National Addiction and HIV Data Archive Program (NAHDAP), currently managed by ICPSR at the University of Michigan.

IPD Sharing Time Frame

The scientific community will be able to access the data at the end of the award period. All publications using the data will also reference the data location in NAHDAP/ICSPR using DOIs. ICPSR engages in long-term preservation of the research data upon receipt of a signed deposit form, including migration to new formats, platforms, and storage media as required. ICPSR has a commitment to designate a successor repository in the unlikely event that such a need arises.

IPD Sharing Access Criteria

To request access, interested researchers will use the standard processes at NAHDAP/ICSPR for requesting data.
