Medical Cannabis Patient Stories in Media Made People More Positive About Recreational Cannabis

Viewing patient narratives about successful medical cannabis use indirectly increased positive attitudes, beliefs, and intentions related to recreational cannabis use by first changing attitudes toward medical cannabis. When patients were presented as not responsible for their illness (external attribution), the effect on medical cannabis attitudes was stronger, which in turn further increased recreational cannabis positivity.

Randomized experiment with 396 Israeli participants assigned to view either a narrative (patient testimonial) or non-narrative video about medical cannabis. Videos were further manipulated by disease stigma and responsibility attribution.

This study demonstrates a "spillover effect" where positive medical cannabis coverage in media influences attitudes toward recreational use. This has implications for both cannabis advocates and prevention programs.

As medical cannabis stories become more common in news and social media, this study suggests they may be shifting public opinion not just about medical use but about recreational use as well. Prevention programs may need to address this media influence.

Israeli sample may not generalize to other cultural contexts. Single exposure to a video - real-world media exposure is cumulative. Measured attitudes and intentions, not actual behavior.
