Internet Search for Illicit Drugs in Italy: Infodemiological Analysis of Six Years of Research

This study explores the potential of Internet search data from Google Trends and Wikipedia as innovative tools for monitoring public interest and behavior related to illicit drug information. Employing a cross‐sectional study design, this research investigates the correlations between search patterns on these platforms and provides insights into public health monitoring. Our analysis indicates significant correlations between searches for various illicit drugs, with correlation coefficients ranging from 0.71 to 0.83, suggesting that these searches can not only reflect but also potentially predict public interest and shifts in drug use patterns. This approach highlights specific periods and demographics showing increased interest in drugs, thereby allowing for targeted public health interventions. The study found that searches related to drugs like cannabis, cocaine, and opioids are not only frequent but also show a tendency to be conducted in tandem, possibly due to synergistic effects. Moreover, the data underscore the importance of providing timely and accurate information to the public through authoritative online sources. With the vast reach of the Internet, ensuring that institutional websites and social networks offer correct information becomes crucial to prevent the spread of misinformation. This study supports Internet‐based data as a complementary tool to traditional drug monitoring systems, which can enhance public health response capabilities by providing real‐time, nonintrusive insights. This research advocates for integrating big data analytics into public health strategy, emphasizing the role of Internet searches in shaping public health policies and practices. The findings suggest that properly leveraged, Internet search data could greatly assist in the precision and effectiveness of public health interventions and preparedness.
