Excessive alcohol consumption, whether chronic or sudden, can lead to serious health issues. To mitigate these risks, it is essential to disseminate accurate information about alcohol consumption while fostering awareness and behavioral change. Previously, we developed a 10-minute video on “Alcohol Metabolism and Genetic Polymorphism” as a tool to aid in the prevention of alcohol-related diseases. We assessed its effectiveness among pharmacy students by administering pre- and post-viewing tests, with results indicating that it served as an effective educational tool within a short period. To extend this educational approach beyond pharmacy students, who generally possess higher levels of expertise and health consciousness, it is necessary to create an illustrated video incorporating visual effects and conduct a survey to evaluate its impact across a wide range of ages. Therefore, in order to clarify the effectiveness of the improved illustrated video lecture, we evaluated it with pre- and post-viewing tests on university festival participants and showed that it can improve the comprehension of people up to their 60s. These data suggest that illustrated video lectures can be an effective educational tool for spreading knowledge on alcohol consumption. Further research is needed to determine whether increased knowledge leads to changes in drinking behavior and prevention of alcohol-related social problems.
