Abstract

Background

The relationship between media portrayal of psychedelic drugs, scientific research and drug policy is an area of debate.

Aims

To apply artificial intelligence technology to measure trends in media sentiment towards the therapeutic potential of psychedelic drugs.

Method

Up to 300 of the most relevant articles from Google News searches for the term ‘psychedelics’ were sampled for each year from 2000 to 2025. A large language model, ChatGPT, evaluated subject matter and sentiment.

Results

In total, 88.3% of screened URLs (3308 of 3747) were included in the analysis. The proportion of articles focusing on the therapeutic potential of psychedelics increased from 13.3% (26 of 198) from 2000 to 2009 to 85.3% (1254 of 1470) from 2020 to 2025. The average sentiment score from 2000 to 2025 for articles from all publications (N = 2168) was 78.5 ± 9.3 (mean ± s.d.) (possible range: 1–100). 1.3% (29 of 2168) of articles carried negative sentiment (<50) whereas 4.8% (103 of 2168) had extremely positive sentiment (≥90). Average sentiment reached a peak in 2020 (80.8 ± 7.0), and a statistically significant trough in sentiment was observed in 2024 relative to 2020–2023 (2020–2023, 79.2; 2024, 74.3, P < 0.00001, Mann–Whitney U-test). The proportion of negative-neutral articles (≤65) increased annually from a trough of 3.6% (8 of 267) in 2020 to a peak of 20.9% (43 of 253) in 2024. Artificial intelligence sentiment scores were correlated and concordant with average human rater scores (r = 0.88, concordance correlation coefficient 0.84).

Conclusions

Although most 21st-century media coverage of psychedelic drugs has been positively framed, negative and neutral coverage has increased in frequency since 2020. Researchers, clinicians, regulators and policy-makers should be mindful of the complex relationship between media portrayals of psychedelics and the results of scientific research.

Fig. 1 Comparison of the performance of artificial intelligence and human raters in measuring media sentiment towards psychedelic drugs. (a) Scatter plot comparing the average artificial intelligence sentiment score for 70 randomly sampled articles with the average sentiment score of human raters (9–10 raters per article). The plotted line represents the theoretical line of complete concordance between artificial intelligence and human ratings. (b) Plots of each individual sentiment score rating for human raters and repeated artificial intelligence iterations for all 70 articles. Each column on the x axis represents an individual article, with articles sorted left to right from lowest to highest average artificial intelligence rating. Black points denote individual artificial intelligence ratings and red points denote individual human ratings. The thickness of borders for individual points represents the number of ratings at a specific sentiment score, with thicker borders indicating more ratings at that score. Black and red bars represent average scores for artificial intelligence and human raters, respectively.

Figure 1

Fig. 2 Changes in media coverage of psychedelic drugs in the 21st century. Black bars represent the total number of URLs appearing in Google News searches for the term ‘psychedelics’, confined to individual calendar years, with totals labelled on the left-hand y axis. The total for the year 2025 is a projection determined by multiplying the total URLs in January–March by 4. The line chart represents the percentage of analysed articles judged by artificial intelligence as primarily pertaining to the therapeutic potential of psychedelic drugs for each calendar year.

Figure 2

Table 1 Examples of artificial intelligence sentiment analysis. Artificial intelligence was asked to rate the positivity of individual articles about the therapeutic potential of psychedelic drugs, on a scale of 1–100, where 100 denotes very positive and 1 very negative. Example artificial intelligence responses are shown

(b) Line chart demonstrating the percentage of all articles with specific sentiment scores from article subgroups.

(a) Average sentiment score for individual years from 2010 to 2025, with bars representing 95% confidence intervals. The year 2025 sampled articles from only 2 calendar months (January and February). (b) Average sentiment score during a period of decline in sentiment from 2020 to 2024, distinguishing between article subgroups. (c) Increases in the absolute numbers (black bars) and percentages of negative-neutral articles (grey line) (sentiment score ≤65) from 2020 to 2024, with the left-hand y axis indicating the total number of negative-neutral articles and the right-hand y axis indicating the percentage of articles. The dashed line indicates the percentage of negative-neutral articles within the entire data-set.
