From 2000 to 2025, media coverage of psychedelic drugs increasingly focused on their therapeutic potential, rising from 13.3% of articles in 2000–2009 to 85.3% in 2020–2025. Overall sentiment was positive, with an average score of 78.5 out of 100. However, negative and neutral coverage has grown since 2020: the proportion of articles with sentiment scores of 65 or below rose from 3.6% in 2020 to 20.9% in 2024, and average sentiment dropped significantly in 2024 compared to 2020–2023. Artificial intelligence sentiment ratings closely matched human ratings.
After adjusting for preexisting psychiatric conditions, the link between hallucinogen use and psychosis disappears. Among 273,466 people with substance-related hospital admissions, psychosis diagnoses were more common after hallucinogen-related admissions (16.4%) than after other substance admissions (6.6%). However, once clinical characteristics were accounted for, the increased risk became nonsignificant (hazard ratio 0.97). This suggests that observed associations between hallucinogens and psychosis are largely due to underlying mental health vulnerabilities, not a direct causal effect. The findings inform psychedelic policy by indicating that population-level data on hallucinogen safety may reflect preexisting risk factors.
