Friends' Use of Marijuana Students Who Reported Having Two or More Close Friends Who Use Marijuana (Grades 10 and 12)

Note: The results are presented as multi-year averages to make them less volatile to year-to-year changes and to account for counties with smaller populations. For the 10th and 12th grade PNA results, Laramie, Niobrara, and Weston Counties participated in one or fewer survey years from 2014 to 2018 and therefore have no results listed in the graph. Albany and Platte Counties had valid results for the 2014 and 2016 PNA survey administrations. Converse, Johnson, Sheridan, and Sublette Counties had valid survey results for the 2014 and 2018 PNA survey administrations. Because of the large number of county response rate concerns in 2020 due to the school closures for COVID-19 mitigation, this graph was not updated to reflect that year's data.
