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.
We assessed the sentiment and themes of a random sample (n = 7,000) of influential marijuana-related tweets (sent from February 5, 20114, to March 5, 2014). Demographics of the users tweeting about marijuana were inferred using a social media analytics company (Demographics Pro for Twitter).
Most marijuana-related tweets reflected a positive sentiment toward marijuana use, with pro-marijuana tweets outnumbering anti-marijuana tweets by a factor of greater than 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 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 with the Twitter average.
Marijuana Twitter chatter sent by influential Twitter users tends to be pro-marijuana 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.
我们试图研究有影响力的推特用户发布的与大麻相关推文的情绪和主题，并描述这些推特用户的人口统计学特征。
我们评估了一个随机样本（n = 7000）的有影响力的与大麻相关的推文（发布于2011年2月5日至2014年3月5日）的情绪和主题。使用一家社交媒体分析公司（推特人口统计学专业版）推断发布关于大麻推文的用户的人口统计学特征。
大多数与大麻相关的推文反映出对使用大麻的积极情绪，支持大麻的推文数量超过反对大麻的推文数量15倍以上。支持大麻的推文中最常见的主题包括推文者表示他/她想要/计划使用大麻，其次是推文提及频繁/大量/经常使用大麻，以及大麻有益健康和/或应该合法化。与大麻相关内容的推文者比推特用户的平均年龄更年轻，非裔美国人的比例更高。
有影响力的推特用户发布的与大麻相关的推文倾向于支持大麻，并且在非裔美国人和青少年/年轻人中很受欢迎。与大麻相关的危害可能会影响一些人；因此，我们的研究结果应用于为线上和线下的预防工作提供信息，这些工作旨在针对那些最有可能受到与使用大麻相关危害的人群。
