Purpose-We sought to examine the sentiment and themes of marijuana-related chatter on Twitter sent by influential Twitter users, and to describe the demographics of these Twitter users.Methods-We assessed the sentiment and themes of a random sample (n=7000) of influential marijuana-related Tweets (sent from 2/5 -3/5/2014). Demographics of the users Tweeting about marijuana were inferred using a social media analytics company (DemographicsPro for Twitter).Results-Most marijuana-related tweets reflected a positive sentiment towards marijuana use, with pro-marijuana Tweets outnumbering anti-marijuana Tweets by a factor of over 15. The most common theme of pro-marijuana Tweets included the Tweeter stating that he/she wants/plans to use marijuana, followed by Tweeting about frequent/heavy/or regular marijuana use and stating that marijuana has health benefits and/or should be legalized. Tweeters of marijuana-related content were younger and a greater proportion was African American compared to the Twitter average.
Conclusions-MarijuanaTwitter chatter sent by influential Twitter users tends to be promarijuana and popular among African Americans and youth/young adults. Marijuana-related harms may afflict some individuals; therefore, our findings should be used to inform online and offline prevention efforts that work to target individuals who are most at-risk for harms associated with marijuana use.
