Trends in adult exclusive and dual use of combustible and non-combustible tobacco products in the United States.
Article in JNCI cancer spectrum, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundAs tobacco use patterns shift toward non-combustible tobacco products such as electronic cigarettes (ECs) and nicotine pouches, dual use with combustible products may undermine potential public health benefits. Herein we describe adult trends in exclusive and dual use of combustible and non-combustible products in the United States between 2015 and 2023.
methodsWe analyzed annual National Health and Interview Survey data including all adults with valid data on tobacco use, age, and sex. Joinpoint regression estimated annual percentage change (APC) and 95% CIs overall and by age group and sex. All tests were 2-tailed (P < .05).
resultsExclusive combustible use remained 2-3 times higher than exclusive non-combustible use or dual use across all years. From 2015 and 2023, combustible use declined in both sexes, with the steepest drops in younger adults after 2020. Exclusive non-combustible use increased in all age groups after 2017, especially among younger adults and females. The most common dual use pattern was cigarettes plus ECs, which was stable over time.
conclusionsExclusive use of combustible tobacco, primarily cigarettes, is declining but remains the most common pattern, especially in older adults. In contrast, exclusive EC use is displacing combustible use among younger adults. Dual use patterns were low overall and stable across the study period.
