Importance: Recreational marijuana use was legalized in the state of Washington in 2012, and the Washington Administrative Code (WAC) 314-55-155 was implemented to limit the exposure of youths to marijuana advertisements.
Objectives: To evaluate the content of social media posts by marijuana companies and to assess the compliance of these posts with WAC regulations.
Design, setting, and participants: In a cross-sectional study, a content analysis of 1027 social media posts was conducted to identify and assess compliance of WAC regulations with the business pages of recreational marijuana companies located on Facebook and Twitter platforms in the state of Washington from December 1, 2015, through November 30, 2016.
Main outcomes and measures: Application of coding based on WAC regulations to focus on the prohibition of language that promoted the overconsumption of marijuana, that described its curative or therapeutic benefits, or that was designed to appeal to youths; and the requirements for warnings about intoxication, driving, health risks, and age restrictions for marijuana.
Results: Of the 1027 posts on Facebook and Twitter from business pages of 6 marijuana companies, Facebook followers ranged from 342 to 1592 persons and Twitter followers ranged from 374 to 2915 persons per company. Findings for WAC regulations included 17 posts (1.7%) that encouraged overconsumption; 137 posts (13.3%) that promoted therapeutic benefits; and 9 posts (0.01%) that appealed to youths. Requirements for warnings addressing intoxication, driving, health risks, and age restrictions were present on 110 posts (10.7%). Some businesses repeatedly violated particular regulations; 7 of 17 (41.2%) posts encouraging overconsumption derived from 1 marijuana company.
Conclusions and relevance: Most social media posts by marijuana companies were consistent with WAC regulations that prohibit particular messages, but few companies provided required warning messages. Findings can be used toward implementation strategies for marijuana prevention to address these influential media messages.
