Campus Smoking Policies and Smoking-Related Twitter Posts Originating From California Public Universities:...

Area of Science:

• Public Health
• Social Media Analysis
• Tobacco Control

Background:

• Increasing adoption of smoke- or tobacco-free campus policies.
• Challenges in assessing policy impact due to evolving tobacco/e-cigarette landscape and varied attitudes.

Purpose of the Study:

• To compare campus climate toward tobacco use via Twitter sentiment analysis.
• Retrospective assessment of universities with and without smoke-free policies.

Main Methods:

• Collected geolocated tweets from California universities in 2015.
• Filtered posts for tobacco-related keywords; analyzed sentiment using chi-square tests.
• Conducted content analysis to identify themes related to policy status.

Main Results:

• Higher positive sentiment toward tobacco use on campuses without smoke-free policies (76.7% vs 66.4%).
• Positive sentiment drivers included general smoking behavior comments.
• Greater tweet type variation observed on campuses without policies.

Conclusions:

• Campus smoke-free policies appear associated with reduced positive sentiment toward smoking.
• Further research needed to understand policy implementation dynamics and tobacco behavioral sentiment.
