How a very-low-nicotine cigarette standard and product prices affect illegal cigarette buying
Official title: Effects of a Low Nicotine Standard and Tobacco Prices on Illegal Cigarette Purchasing
Run by Virginia Polytechnic Institute and State University · NCT07161050 · Data updated 2026-11-12
This study will test whether requiring very-low-nicotine cigarettes and changing e-cigarette or illegal cigarette prices changes illegal cigarette buying and use of alternatives among adult smokers and dual users.

Is this trial a fit for you?
✓Likely a good fit
Adults aged 21 or older who smoke at least 10 cigarettes per day and are either exclusive smokers or regular dual users of cigarettes and nicotine vaping products, and who can attend three in-person sessions, are the intended participants.
✕Probably not a fit
People who are pregnant or lactating, planning to quit immediately, have unstable medical or psychiatric conditions, or are taking medications that affect nicotine metabolism are excluded and unlikely to benefit from participation.

What this trial studies
Researchers will bring adult exclusive cigarette smokers and dual cigarette/vaping users into a lab to complete an experimental virtual marketplace where legal and illegal product availability and prices are varied. Participants will complete three sessions (screening/assessment, the experimental tobacco marketplace session, and a follow-up phone call) and encounter scenarios comparing normal-nicotine and very-low-nicotine legal conditions. The experiment manipulates three levels of e-cigarette price and three levels of illegal cigarette price to see how those factors influence purchasing of illegal products and alternative nicotine product use. Outcomes will include choices made in the marketplace under each condition and differences by smoking/vaping status and age strata.
Why it matters
Potential benefit: If successful, the results could help regulators design nicotine standards and pricing policies that reduce harmful smoking while minimizing shifts to illegal cigarette markets.
How similar studies have gone: Previous laboratory and experimental marketplace studies of very-low-nicotine cigarettes and price changes have shown reductions in cigarette use, but effects specifically on illegal cigarette purchasing are less well established.
