Spanish-language Twitter discourse heavily favored cannabis regulation while underemphasizing health risks
Analysis of nearly 36,000 Spanish-language tweets about cannabis found 73% favored regulation while only 20% discussed negative health effects, revealing a pro-legalization bias in online discourse.
Quick Facts
What This Study Found
Among 35,527 analyzed Spanish-language tweets about cannabis (2018-2022), 73.2% favored cannabis regulation while only 3.5% expressed opposition. Only 20.4% discussed negative effects on physical or mental health. Regarding therapeutic use, 30.1% were in favor while 69.9% were neutral or against. Significant differences emerged between user types and between cannabis consumers versus non-consumers.
Key Numbers
68,673 total tweets; 35,527 analyzed; 73.2% favored regulation; 3.5% opposed; 20.4% discussed negative health effects; 30.1% supported therapeutic use; tweets from 2018-2022
How They Did This
Dataset of tweets posted 2018-2022 in Spanish containing keywords "cannabis," "marihuana," or "hachis." A 500-post subset per keyword was manually coded to establish a codebook, then machine learning classified the remaining 67,173 tweets. After excluding irrelevant tweets, 35,527 were analyzed.
Why This Research Matters
Social media shapes public perception of cannabis, and the significant imbalance between pro-regulation content (73%) and health risk discussion (20%) suggests online discourse may not reflect the full scientific picture. This has implications for how the public forms opinions about legalization.
The Bigger Picture
As more Spanish-speaking countries and regions consider cannabis regulation, the online information environment is heavily weighted toward pro-legalization perspectives with limited health risk discussion. This mirrors patterns seen in English-language social media and may influence policy decisions.
What This Study Doesn't Tell Us
Twitter users are not representative of the general population. Machine learning classification may misclassify tweets. Spanish-language tweets span multiple countries with different cultural contexts and legal frameworks. 2018-2022 timeframe may not reflect current discourse.
Questions This Raises
- ?Does the pro-regulation bias in social media discourse influence public health policy outcomes in Spanish-speaking countries?
- ?Would health-focused counter-messaging on social media change public risk perception?

What do these levels mean? →Frequently Asked Questions
Why does this matter for public health?
If most online cannabis discourse emphasizes legalization benefits while downplaying health risks, people forming opinions through social media may develop an incomplete understanding of the tradeoffs involved in cannabis regulation.
Did consumers and non-consumers tweet differently?
Yes. The study found significant differences in perspectives between cannabis consumers and non-consumers, as well as between different types of Twitter users, though specific differences were not detailed in the abstract.
