These interactive maps are designed to highlight substance use rates among 8th and 11th graders in Delaware. Substance rates were collected using the Delaware School Survey data for the 2015-2016 and 2016-2017 school year. Substance rates include past month rates of alcohol use, past two week binge drinking, past month marijuana use, past month cigarette use, past year prescription drug use, and past year rates of prescription pain killer use are displayed by zip codes. The lighter yellow zip codes represents areas of lower use, while bolder red zip codes represents areas of higher use. Below you will find two links to the Delaware interactive heat map, and you will find a tutorial with screen shots to help guide you through the interactive map. The last link provides a map presenting the geographical distributions of after school program resources as well as teen substance use rates.
