Back in 2010, California attracted national attention by putting a measure to legalize cannabis on the ballot. Many questions about the implications of the measure were directed at Erick Eschker, professor of economics at Northern California’s Humboldt State University. If anyone could provide answers about the size of the local cannabis industry, or the economic impact of Prop 19, they figured it would be Eschker and his colleagues. Unsure of how the legalization process would work, Eschker helped create The Humboldt Institute for Interdisciplinary Marijuana Research, a collection of faculty that conducts research about cannabis policy that he now co-directs. Humboldt State University is a natural fit for research into the economic and cultural effects of cannabis; it’s in one of three counties that comprise the famous Emerald Triangle, which has been called the cannabis-growing capital of the U.S. for years.
