Substance use among second-generation immigrants in France: heritage language as a protective factor.
Article in International journal of public health, 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
Objectives: Study substance use among second-generation immigrants in France (G2) in comparison with first-generation immigrants (G1) and majority population, and particularly the variation according to practice of heritage language. Methods: in a nation-wide probability sample, we focused on the two largest groups (from Maghreb and Southern-Europe: n = 2,736), analysing their use of alcohol, tobacco and cannabis. The main factor of interest was practice of heritage language at home at age 15 (vs. exclusive use of French), and we also considered type of parentage: homogenous (two immigrant parents from the same country) vs. mixed (only one, the other being French). Results: In comparison with the majority population (neither G1 nor G2: n = 19,185), G1 had lower levels of substance use, followed by G2 speaking the heritage language and by G2 with homogeneous parentage. The other G2 reported higher levels of substance use, close to those of the majority population (even higher for tobacco among Maghrebins and cannabis among South-Europeans). These associations remained robust after adjusting for potential individual and contextual confounding variables. Conclusion: Integrating those specificities may help in designing culturally grounded prevention policies benefitting the population at large.
