What happens when a friend starts talking about her own substance use and misuse? This article provides the first investigation of how substance use is spontaneously topicalized in naturally occurring conversation. It presents a detailed analysis of a rare video-recorded interaction showing American English-speaking university students talking about their own substance (mis)use in a residential setting. During this conversation, several substance (mis)use informings are disclosed about one participant, and this study elucidates what occasions each disclosure, and how participants respond to each disclosure. This research shows how participants use casual conversation to offer important substance (mis)use information to their friends and cohabitants, tacitly recruiting their surveillance. Analysis also uncovers how an emerging adult peer group enacts informal social control, locally (re-)constituting taken-for-granted social norms and the participants’ social relationships, to on the one hand promote alcohol use while, on the other hand endeavouring to prevent one member from engaging in continued pain medication misuse. This article thus illuminates ordinary peer conversation as an important site for continued sociological research on substance (mis)use and prevention.

关于物质（错误）使用的同行对话

当朋友开始谈论她自己的物质使用和滥用时会发生什么？本文首次调查了物质使用如何在自然发生的对话中自发地成为话题。它详细分析了一个罕见的视频录制互动，显示美国说英语的大学生在住宅环境中谈论他们自己的物质（误）使用。在这段对话中，一些物质（MIS）使用informings披露关于一个参与者，而这项研究阐明什么场合每个披露，以及参与者如何响应每一次披露。这项研究展示了参与者如何使用随意的谈话向他们的朋友和同居者提供重要的物质（误）使用信息，暗中招募他们的监视者。分析还揭示了一个新兴的成人同龄人群体如何制定非正式的社会控制，在当地（重新）构成理所当然的社会规范和参与者的社会关系，一方面促进饮酒，另一方面努力防止一名成员继续滥用止痛药。因此，本文将普通的同伴对话阐明为继续对物质（误）使用和预防进行社会学研究的重要场所。
