The top two user categories were everyday people (65{\%}) and individuals who are part of the e-cigarette community movement (16{\%}). These two user groups were responsible for a majority of informational (79{\%}) and news tweets (75{\%}), compared to reputable news sources and foundations or organizations, which combined provided 5{\%} of informational tweets and 12{\%} of news tweets. Personal opinion (28{\%}), marketing (21{\%}), and first person e-cigarette use or intent (20{\%}) were the three most common genres of tweets, which tended to have a positive sentiment. Marketing was the most common theme (26{\%}), and policy and government was the second most common theme (20{\%}), with 86{\%} of these tweets coming from everyday people and the e-cigarette community movement combined, compared to 5{\%} of policy and government tweets coming from government, reputable news sources, and foundations or organizations combined. Conclusions: Everyday people and the e-cigarette community are dominant forces across several genres and themes, warranting continued monitoring to understand trends and their implications regarding public opinion, e-cigarette use, and smoking cessation. Analyzing social media trends is a meaningful way to inform public health practitioners of current sentiments regarding e-cigarettes, and this study contributes a replicable methodology.
