Nicotine-Cannabis Transitions and Nicotine Abstinence Among United States Adults.

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
backgroundPrior studies examining the association of cannabis use with nicotine abstinence did not distinguish between individuals co-using nicotine and cannabis versus those who switched from nicotine to exclusive cannabis use; these may have different effects on nicotine abstinence. We examined associations of cannabis use uptake with subsequent nicotine abstinence approximately 1 year later among adults using cigarettes and/or e-cigarettes.
methodsUsing six waves of the Population Assessment of Tobacco and Health Study (2013-2021), we assessed transitions from exclusive nicotine use prebaseline (time t ) to (1) exclusive cannabis use, (2) nicotine-cannabis co-use, (3) nonuse of both nicotine and cannabis, and (4) continued exclusive nicotine use at baseline ( t + 1) as exposure variables. Analyses examined associations with nicotine abstinence (from both cigarettes and e-cigarettes) at 1-year follow-up ( t + 2).
resultsAmong 8382 adults (19,618 observations) reporting exclusive nicotine use prebaseline, 1% transitioned to exclusive cannabis use, 9% to nicotine-cannabis co-use, and 9% to nonuse of both drugs; 81% were still using nicotine exclusively at baseline. Transition to nicotine-cannabis co-use (6%) versus exclusive nicotine use (10%) was inversely associated with nicotine abstinence at follow-up (adjusted relative risk [aRR] = 0.68; 95% confidence interval [CI] = 0.55, 0.83). Transition to exclusive cannabis use (72%) was positively associated with nicotine abstinence compared with continued exclusive nicotine use (10%; aRR = 4.66; 95% CI = 3.83, 5.67) and with similar nicotine abstinence at follow-up (72%) compared with nonuse of both drugs (65%; aRR=0.98; 95% CI = 0.81, 1.18).
conclusionCo-use of nicotine and cannabis was associated with lower nicotine abstinence. Switching to exclusive cannabis use was associated with similar or greater nicotine abstinence.
