Geographer Investigates Marijuana Price Distribution

HSU geographer Monica Stephens presents “Data Shadows of the Underground Economy,” in the latest installment of the Humboldt Interdisciplinary Institute for Marijuana Research speaker series. The talk takes place on Tuesday, January 29, in the Native Forum (Behavioral and Social Sciences Building, Rm. 162) from 5:30 to 7 p.m.

In her talk, Stephens will discuss the distribution of marijuana prices in various regions and the value of volunteered geographic information with studies that could not be conducted otherwise.

At the site’s organizers request that volunteers contribute the prices paid for marijuana and the location of purchase. “This site, along with statistical measures used to model the price, demonstrates that within the U.S. there is a geography to marijuana pricing characterized by lower prices in states with medical marijuana programs and higher prices farther from such areas,” says Stephens.

Stephens will also discuss the project as a recent study in the field of volunteered geographic information. VGI refers to map users adding geographic information to an existing base map.

Monica Stephens lectures in the Geography Department at Humboldt State University. Her research focuses on social and geographic inequalities in online content. Stephens blogs at and has published maps in Wired Magazine, The Guardian, CNN, Gizmodo, The Atlantic, The Atlantic Cities, the BBC, Slate, the Huffington Post, and elsewhere.
