Cocaine Use Related to Level of Education

Johns Hopkins Bloomberg School of Public Health - Cocaine use has dropped in the United States over the last 20 years, but mostly among the highly educated. Cocaine use among non-high school graduates remained constant, a bad sign, according to a study by researchers at the Johns Hopkins Bloomberg School of Public Health.


The researchers suspect that the relationship between more constant cocaine use and education is due to limited access to health warnings and resources. They suggest that their findings highlight a need for improved interventions targeting cocaine users who are lower educated. The study is published in the October 2007 issue of the American Journal of Public Health.


“Much like smoking, people with a better understanding of the impact cocaine has on health are more likely to modify their behavior,” said Valerie S. Harder, MHS, lead author of the study and a PhD-candidate in the Bloomberg School of Public Health’s Department of Mental Health. “Better educated individuals also may have more resources and access to health care services, such as drug treatment programs.”


The researchers used data from the 1979-2002 National Survey on Drug Use and Health to compare cocaine use and educational achievement for adults aged 19-50 years. Adults were categorized as non-high school graduate, high school graduate or college graduate and as either recent-onset or persistent cocaine users.


The proportion of non-high school graduates using cocaine has remained consistent from 1979-2002. Early data suggests that high school and college graduates were more likely to start and persist in their use of cocaine, as compared to non-high school graduates. During the late 1980s, the proportion of high school and college graduates classified as persistent users dropped dramatically and fell below that of non-high school graduates. During the same time period, first time cocaine use steadily decreased among all adults regardless of their level of educational achievement and remained low.

“It isn’t enough to simply try to stop individuals from using cocaine the first time,” said Harder. “More drug intervention programs that target non-high school graduates are necessary to reduce persistent cocaine use in that population.”


Howard D. Chilcoat, ScD, an associate professor in the Johns Hopkins Bloomberg School of Public Health, co-authored the study.
