Social media and other digital technology use facilitate connection among adolescents, but also may reinforce norms and substance-related content from peers and advertisers. We use nationally representative data to examine the association between digital technology and past 30-day use of alcohol, cannabis, and vaping.
Data were drawn from the 2018 Monitoring the Future survey of US adolescents (N = 44,482). Poisson regressions estimated the association between hours/day of technology use and past 30-day use of alcohol, cannabis, and vaping adjusting for grade, sociodemographics, and other past-year drug use.
Across grades, mean hours of social media/day was 3.06 (standard deviation = 2.90), past 30-day alcohol, cannabis, flavor vaping, cannabis vaping, and nicotine vaping were 15.7 %, 12.6 %, 10.6 %, 4.9 %, and 11.2 %, respectively. Digital technology use that required interaction with others was associated with increased risk of past 30-day drinking, cannabis use, and vaping. For example, social media 3+ hours/day was associated with past 30-day drinking (adjusted relative risk [aRR]: 1.99, 95 % CI: 1.65, 2.41). The magnitude of association was consistent across texting, phone calls, and video chatting, which were all more strongly associated with substance use than with activities that do not require interaction such as gaming and watching videos.
Digital technology that facilitates interaction among adolescents, such as texting and social media, is associated with past substance use. Magnitudes of association are consistent across substances, supporting the hypothesis that networks of adolescents are social drivers of substance use, rather than the technology itself.
社交媒体和其他数字技术的使用促进了青少年之间的联系，但也可能强化来自同龄人和广告商的规范及与物质相关的内容。我们使用具有全国代表性的数据来研究数字技术与过去30天内酒精、大麻和电子烟使用之间的关联。
数据来自2018年美国青少年未来监测调查（N = 44,482）。泊松回归估计了每天技术使用小时数与过去30天内酒精、大麻和电子烟使用之间的关联，并对年级、社会人口统计学特征以及过去一年的其他药物使用情况进行了调整。
在各个年级中，社交媒体的日均使用时长为3.06小时（标准差 = 2.90），过去30天内酒精、大麻、调味电子烟、大麻电子烟和尼古丁电子烟的使用率分别为15.7%、12.6%、10.6%、4.9%和11.2%。需要与他人互动的数字技术使用与过去30天内饮酒、使用大麻和吸电子烟的风险增加有关。例如，每天使用社交媒体3小时以上与过去30天内饮酒有关（调整后的相对风险[aRR]：1.99，95%置信区间：1.65，2.41）。短信、电话和视频聊天的关联程度一致，与物质使用的关联都比与不需要互动的活动（如游戏和观看视频）更强。
促进青少年之间互动的数字技术，如短信和社交媒体，与过去的物质使用有关。不同物质的关联程度一致，支持了青少年社交网络是物质使用的社会驱动因素而非技术本身这一假设。
