Popular media reports on Tobacco 21 laws demonstrated average overall quality and relied on both anecdotal and scientific evidence, in contrast to previous studies found that popular media reports on tobacco issues demonstrated low overall quality and relied primarily on anecdotal evidence. The systematic review of increased MLAs for tobacco written by the Institute of Medicine diffused quickly into popular reporting, suggesting that this type of evidence might improve research translation.
