Abstract
The rise of social media raises concerns about the dissemination of misinformation regarding cannabis. This has become problematic, particularly among young adults aged 18-26 who rely on social media as a source of various health information. The glamorized representation of cannabis on these platforms and the thriving market promoting unverified health claims further contribute to an increased risk of early initiation among this age group. Despite the significance of this issue, there is a noticeable gap in understanding the influence of social media on cannabis misperception, and thus behavioral intention among this demographic. Media literacy has proven to be a protective factor in mitigating misinformation effect on behaviors. This study developed new social media literacy skills based on knowledge and competence. Based on the media literacy theory of change and social cognitive theory, this study investigated the associations among social media dependence, social media literacy specific to knowledge and competence, and misperceptions of cannabis, expectancies, and behavioral intentions related to cannabis. This study found that the perceived usefulness of social media leads to higher misperceptions about cannabis. Social media literacy skills for content and production are important to mitigate cannabis misperceptions. Misperceptions were a precursor of cannabis expectancy and behavioral intention. There is a critical need for targeted media literacy interventions that empower young people to navigate information effectively and actively contribute to creating a healthier media environment. This study suggests the importance of equipping young adults with the knowledge and competencies needed to critically engage with cannabis-related content on social media. The newly developed media literacy measures provide a valuable insight for health communication research by providing a context-specific tool.
