Racialization of the drug trade has been an ongoing feature of drug‐related moral panics for over a century. In the latter part of the twentieth century, public anxieties about ongoing economic changes made immigrants and Mexican drug cartels convenient scapegoats in the context of moral panics about cannabis and cannabis growers. In this research, I focus on the social construction of cannabis growers in the Emerald Triangle of Northern California, with a particular focus on the cartel grower construct. Through a content analysis of news media coverage, government and law enforcement reports, and field notes from personal communications with law enforcement officers and government officials, I identify racialized constructions of growers in the region. I also explore the relationships between local narratives and the broader cannabis discourse. In this “post‐prohibition” moment, this discourse impacts U.S. cannabis policy conversations and fuels anti‐immigrant rhetoric.
