Cigarette smoke exposure greatly increases alcohol consumption in adolescent C57BL/6 mice.
Article in Alcoholism, clinical and experimental research, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers.
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
backgroundAlcohol and tobacco are often used together, and alcoholism is much more common among smokers compared with nonsmokers. Studies in humans suggest that nicotine (an active ingredient in cigarette smoke) can increase the consumption of alcohol. Research on rats and mice demonstrated mixed results; some studies report that nicotine increases alcohol consumption, while others show a decrease in drinking. Because cigarette smoke includes many other chemicals, these also may play a significant role in alcohol consumption. For example, 2 of these other constituents, monoamine oxidase inhibitors and acetaldehyde, increase alcohol tolerance and/or alcohol consumption in rodents. This study was designed to investigate how cigarette smoke from tobacco may modify self-administration of alcohol in adolescent C57BL/6 mice, a critical time when adolescent humans begin abusing drugs.
methodsC57BL/6 male mice (4 to 5 weeks old) were acclimated for 3 weeks to consume a 10% (w/v) alcohol solution during a 2-hour daily access in the dark. Subsequently, half the animals were exposed to cigarette smoke for 6 h/d for 16 days. The remaining animals (control) were placed in a smoke-free adjacent chamber. Immediately following the 6-hour period in the chambers, the control and smoke-exposed mice were given access to the 10% alcohol solution for 2 hours.
resultsAnimals exposed to cigarette smoke for 6 h/d consumed approximately 3- to 5-fold more alcohol than the mice in the control group throughout the 16-day study. The mice in the smoke group had a blood alcohol concentration that was nearly 4-fold that of the control mice.
conclusionsCigarette smoke increases alcohol consumption several fold higher than reported studies using nicotine treatment alone in adolescent rodents. Thus, this model should be useful to determine the roles of other bioactive components in cigarette smoke that may be important in the high co-abuse of smoking and alcohol consumption.
