Better education: The anti-drug

Diplomas and advanced degrees have long been associated with higher incomes, but a new study suggests a link between education and lower cocaine use.

“Over the last 20 years, we found that the number of new users of cocaine has been steadily decreasing,” said Valerie S. Harder, a Ph.D. candidate at Johns Hopkins Bloomberg School of Public Health. “And when we split it up by education, we found that individuals who don?t ever graduate from high school seem to have had a constant level of cocaine usage” during the same period.
