A Bengo hemp plantation shows Africans smoking dry cannabis in 1803

In 1803, near the Bengo river in what is now Angola, there stood a hemp plantation promising a good harvest — proof, to the Portuguese administration, that the land suited the crop.^[1] The same plant was already in African hands: Black cultivators grew it, smoked it dry, and intoxicated themselves, in the administrator’s words, “in a terrible and disastrous way”.^[1]

Fibre hopes, smoking reality

The plantation embodied a colonial hope: that Angola could grow European-style fibre hemp.^[2] The Africans’ use embodied something else entirely — a smoking culture the Portuguese could only describe through the vocabulary of damage.^[2] Satisfaction at the promising harvest and horror at African smoking sit in the same paragraph: one plant, two economies.^[2][1] Duvall renders their phrase as a “terrible and disastrous” use of canhâmo, the Portuguese word for European hemp, now stretched to cover a drug plant.^[2]

A crop among crops

Saldanha’s page sets the plantation in a working foodscape: millet ground into fuba, sugarcane, sweet cassava as the people’s staple, yams and beans around the town — and the hemp plot among them.^[1] Cannabis travelled inside ordinary farming.^[2] By 1832 a French traveller found it common around Bailundo, an inland slave-market town, grown as part of cropping systems farmers kept adapting to drought, warfare and population shifts — planted as widely as manioc, maize, calabash, melons, tomatoes and tobacco, though rarely in abundance.^[2]

The earliest Atlantic record

Duvall treats the 1803 notice as the start of the plant’s documented history in western Central Africa.^[2] It is also the earliest documented presence of cannabis in the tropical Atlantic world, centred on the Luanda hinterland where Portuguese administrators first confronted large-scale African cultivation for smoking rather than fibre.^[2]

The record then goes quiet for half a century until Livingstone’s 1857 observations pick up the story further inland.^[2] The full arc continues on Angola’s page.^[2]
