Anthropologists compare cannabis traditions at a Chicago conference

In August 1973, a conference in Chicago brought together researchers to compare cannabis across societies. It met during the Ninth International Congress of Anthropological and Ethnological Sciences, with about sixty scientists attending, according to organiser and editor Vera Rubin.

The resulting volume, Cannabis and Culture, appeared in 1975. Its chapters preserve a research programme that treated cannabis as a plant with economic, linguistic, religious and household roles, alongside the public controversies surrounding its intoxicating effects.

Comparing practices rather than assuming one use

The conference’s objectives included assembling ethnobotanical and historical evidence, locating researchers familiar with traditional uses, comparing social settings and reviewing national commissions and legal questions.

The subjects were deliberately varied. The published collection included African and Asian plant histories, Rif agricultural livelihoods, Jamaican social networks, Mexican ritual and European folk customs. It also included medical and pharmacological studies and comparisons with other psychoactive plants.

Those subjects were not interchangeable. Hemp seed in a household dish, cannabis used in a religious ceremony and commercial production for fibre involved different materials, expectations and institutions.

Rubin’s two cultural complexes

Rubin proposed a distinction between a multifunctional traditional stream, which she called the ganja complex, and a newer marihuana complex associated with Western youth and interest in altered experience.

The distinction was an interpretive framework, not a finding that every society or user belonged neatly to one category. The chapters themselves contain differences within communities, competing interpretations and social changes that resist such a simple division.

Her introduction also emphasised the importance of social class: a practice could be accepted within a working community while attracting condemnation from more powerful groups. The volume consequently supplies evidence about stigma and authority as well as about consumption.

Research and its limits

Rubin identified problems in comparing studies that did not adequately describe the cannabis used, its THC content, frequency of consumption, participants’ histories or the selection of controls. Her discussion is a reason to read the chapters with attention to their methods, rather than treating the collection as a single verdict on the plant.

The book also contains hypotheses about ancient diffusion, linguistic origins and medicine. Publication in an influential collection does not settle those questions, and its clinical claims should not stand in for present medical evidence.

A source for later historical work

The conference was a scholarly gathering, not a legislature, court or treaty meeting. No legal change follows from its occurrence alone.

Its contribution to cannabis history lies in the records it assembled. The atlas now uses individual chapters, with printed page references, to distinguish directly observed practices from reported beliefs and later interpretation. Local copies can support further research without making the book itself part of the published website.^[1][2]
