This study is proposing a four condition Electronic Tobacco Marketplace (ETM) study to determine if banning normal nicotine content (NNC) is sufficient for encouraging smokers to switch to potentially less harmful products or if the availability of higher nicotine and/or flavored alternative products (specifically e-cigarettes) are needed to achieve maximal reductions in smoking.

The Family Smoking Prevention and Tobacco Control Act (FSPTCA) passed in 2009 provides the FDA with the authority to regulate tobacco products. One provision in this legislative act empowers the FDA to set limits on constituents in tobacco products, including nicotine. Such a measure has the potential to reduce the chance of individuals experimenting with smoking from becoming dependent and enable current smokers to quit when they are motivated to do so. Although the proposal to reduce nicotine in cigarettes has been met with skepticism by some because of concerns over compensatory smoking behavior and the potential emergence of a black market, this policy measure was considered to be technically feasible by the American Medical Association and the British Medical, by tobacco control researchers, policymakers and governmental officials who were convened in a meeting on nicotine regulation8, and by the World Health Organization Study Group on Tobacco Product Regulation. Most importantly, in July 2017, FDA Commissioner Gottlieb announced he was "directing our Center for Tobacco Products to develop a comprehensive nicotine regulatory plan premised on the need to confront and alter cigarette addiction." This announcement was followed on March 16, 2018 by the release of the Advance Notice of Proposed Rulemaking entitled "Tobacco Product Standard for Nicotine Level of Combusted Cigarettes" (ID: FDA-2017-N-6189-0001) "to obtain information for consideration in developing a tobacco product standard to set the maximum nicotine level for cigarettes."
This study proposes to conduct a within-subjects, multi-session virtual lab study and validation field assessment to determine how the availability of flavored e-liquids affects product purchasing among cigarette smokers. Adult daily cigarette smokers (N=64) will be recruited for this study. After initial eligibility is assessed, participants will complete six virtual sessions (1 baseline, 4 experimental, and 1 follow-up) and one field assessment to evaluate their tobacco use.

Time frame: Visit 6 approximately 4 weeks after baseline
Average number of cigarettes purchased (analyzed as raw data and using derived behavioral economic measures)
Time frame: Visit 6 approximately 4 weeks after baseline
Average number of e-liquid milliliters purchased (analyzed as raw data and using derived behavioral economic measures)
Time frame: Month 1 after baseline
The proportion of participants projected to choose a cigarette over an e-cigarette under different potential regulatory scenarios, as determined by regression analysis.
Time frame: Baseline
The response options rely on a 10-point Likert-like scale: 1 = very low risk of disease; 2, 3, 4, 5, 6, 7, 8, 9, 10 = very high risk of disease. Minimum possible response 1. Maximum possible response 10. The higher the score, the greater perceived risk of VLNC cigarettes for lung cancer.
Time frame: Visit 6 approximately 4 weeks after baseline
Product evaluation scale scores for VLNC cigarettes among participants who received VLNC cigarettes will be determined by a product evaluation questionnaire. The questionnaire measures the strength of self-reported positive subjective effects (e.g., reward, satisfaction) following product use. The response options rely on a 7-point Likert-like scale: 1=not at all; 2= very little; 3= a little; 4= moderately; 5= a lot; 6= quite a lot; 7= extremely. The summed score adds responses to 13 separate items. Minimum possible response: 13. Maximum possible response: 91. Higher scores denote more favorable product effects. Note: This was only administered (at Virtual Visit 6) to participants who received each product type in the field (dependent on their baseline ETM shopping trip purchases).
Time frame: Visit 6 approximately 4 weeks after baseline
Minnesota Nicotine Withdrawal Scale measures the severity of nicotine withdrawal symptoms. The response options rely on a 5-point Likert-like scale; 0=None; 1= Slight; 2=Mild; 3=Moderate; 4=Severe. There are 7 items total, that are summed. Minimum possible response: 0. Maximum possible response: 28. Higher scores denote greater severity of withdrawal symptoms.
Time frame: Visit 6 approximately 4 weeks after baseline
Questionnaire on Smoking Urges measures the strength of urges to smoke. The response options rely on a 7-point Likert-like scale: 1=Strongly Disagree; 2; 3; 4; 5; 6; 7= Strongly Agree. The questionnaire has 10 total items; scores sum responses to each item. Minimum possible response: 10. Maximum possible response: 70. Higher scores denote greater urges to smoke.
Time frame: 1 month after baseline
Tobacco Product Interest of different products; Slider scale ranging from 0=No Interest to 100=Very Interested
Time frame: 1 month after baseline
Tobacco Policy Questionnaire scored from Support, Oppose, and Don't know for personal opinions on Making Cigarettes Less Addictive
Time frame: Screening visit through end of study (up to week eight)
Participants are asked about their opinions and experiences using tobacco products other than their usual brand during the field assessment.
Time frame: Screening visit through end of study (up to week eight)
Participants are asked what products they had used and quantity every day during the field assessment.
Time frame: Screening visit through end of study (up to week eight)
Product use and biomarkers of exposure during the field assessment will be analyzed using linear regression or other appropriate regression models. The model for primary analysis of these data will include main effects for each of the two factors (for the ETM condition carried into the field assessment), and the corresponding baseline measure to improve precision. Carbon Monoxide (CO) is collected in ppm.
