Cannabis Use During Pregnancy: Insights from Online Discourse and Socioeconomic Indicators Across the USA and Canada

Abstract

Cannabis use is on the rise, driven by relaxing legal regulations and declining perceptions of harm. This trend, coupled with the increasing reliance on social media for health-related information, has sparked interest in cannabis use during pregnancy (CanPreg). This study examines online discourse about CanPreg on Twitter, analyzing 53,183 unique tweets from 32,744 users in the USA and Canada between 2012 and 2021. We investigate the spatio-temporal distribution of CanPreg discussions, key topical contexts within these conversations, and their correlations with socioeconomic and health indicators. The analysis reveals regional differences, with a relatively higher interest in CanPreg discussions in Canada compared to the USA. The online discourse is primarily focused on research, alongside criticism, personal experiences, queries, news sharing, and advertisements. Additionally, correlations between CanPreg tweet activity, poverty rates, and mental health metrics suggest a connection between online discussions and real-world behaviors. This study highlights the role of social media in health communication and provides insights to inform targeted intervention strategies.
