A literature review in Health & Place by researchers at The Ohio State University School of Public Health synthesized evidence on density-reduction policies. Findings indicate that prohibitions on tobacco sales in pharmacies reduced retailer density, but perhaps not equitably. Prohibiting the sale of tobacco near schools produced greater density reductions in higher-risk neighborhoods, and a combination of policies was most effective. “Density-reduction policies offer a promising approach to tobacco control,” the authors concluded. The paper provides a nice overview of density-reduction options, including some interesting twists and survey data on attitudes toward them. Read the paper.
