1 · What the graph read from it

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.

2 · The registry

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

introductionTobacco and cannabis are commonly co-used (i.e., used concurrently or co-administered) but rarely 'co-addressed' and few co-use interventions exist. Young adulthood presents a key age for intervening in substance use, therefore understanding young adults' perspective is crucial, but little is known about how they understand or experience co-use. This study aimed to explore factors influencing co-use and changes to use within a population of young adults in the UK.

methodsParticipants were young adults recruited via three Further Education (vocational) colleges, who reported past 6-month co-use. Individual semi-structured interviews were carried out and analysed using the Framework approach.

resultsEighteen participants were interviewed. Analysis identified influential factors, comprising three categories: (i) identity and social context including the concept of co-use; (ii) experiences; and (iii) understanding of effects. Family and peers were an important influence on use and cessation and young adults used their observation of peers' experiences to understand potential harms of each substance, as well as the complex relationship between cannabis use and mental health. DISCUSSION AND

conclusionsA broad range of factors influence co-use, and changes made to co-use, of tobacco and cannabis in young adults. Further investigation is needed to inform the development of co-use interventions. Credible co-use health risk information relevant to young adults, and the role of co-occurring mental health challenges need consideration in the development of co-use interventions.
