Listen to My Talk - Purity and pollution: Cannabis as matter out of place

In September, I gave a talk entitled Purity and Pollution: Cannabis as Matter Out of Place at the Phoebe Hearst Museum of Anthropology. It was part of their Cannabis in Context series, which featured talks on US cannabis policy, cannabis and warfare in the Democratic Republic of Congo, the neuroscience of cannabis, the rise of CBD and negative experiences with edibles. In my talk I finally got to dig into some field notes on quality and safety testing laboratories, how they differentiate what is safe from what is dangerous, pure from impure, quality from inferior and then to extrapolate this framing to my other work on blight, nuisance, and the politics of environmental harm. Take a listen!
