After categorizing search terms as \u201cHealth Information Seeking\u201d (HIS), \u201cPro-tobacco\/Nicotine\u201d (PtN), or Ambiguous, a content analysis of N = 606 relevant videos identified pro-versus anti-tobacco videos by tobacco manufacturer, broadcast media, health institution, and organic sources. Analyses describe how often each kind of search leads to each kind of source and to pro-tobacco videos in both the primary search results and the recommended videos.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>In sum 394(65%) videos were pro-tobacco including 83% of PtN and 60% of ambiguous searches. However, just 5 of 118 videos returned by HIS searches or recommendations were pro-tobacco. Tobacco manufacturer videos were primarily found in PtN searches, though two were recommended in ambiguous searches. The most common primary search results for HIS were health institutions comprising 39% of combined primary (45%) and recommended (36%) videos.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Although possible, tobacco and nicotine related HIS on YouTube is unlikely to drive exposure to pro-tobacco content and relatively likely to lead to reputable sources such as health institutions.
