4. Interpretation
“Because adolescents age 15 to 18 years are exposed to an average of 2.4 hours of popular music per day, our results suggest that the average adolescent is exposed to approximately ,732 references per year. This represents a pervasive source of exposure to positive portrayals of substance use. Furthermore, exposure varies substantially be genre: the average adolescent listening wholly to pop would be exposed to 5 references per day, whereas the average adolescent listening wholly to rap would be exposed to 251.” p. 24
