The law mandates hospitals to collect samples via qualified medical personnel (like doctors or nurses) and send them to the health science center for analysis. The health science center must study drug interactions from the samples and include findings in quarterly reports to lawmakers. This applies to mass shootings occurring on or after July 1, 2026.
