Cannabis Culture in Sub-Saharan Africa During the 1910s

Cannabis in Africa before the 1910s: the baseline

Cannabis reached Sub-Saharan Africa long before European colonization, most likely via Arab and Swahili trade routes along the East African coast and across the Sahel between roughly the 13th and 16th centuries ^[1][2]. By the time European observers began writing systematic accounts in the 19th century, cannabis smoking was well-established among Khoisan groups in the Cape, several Bantu-speaking societies in Southern Africa, communities along the Zambezi, parts of the Congo Basin, and pockets of East Africa ^[1][3]. Portuguese sources from Angola and Mozambique recorded liamba and diamba use as routine ^[1] Strong evidence.

This matters because the 1910s did not introduce cannabis to Africa — they introduced systematic state efforts to control it.

Regional patterns in the 1910s

Southern Africa. Dagga was grown in the eastern Cape, Natal, Basutoland (Lesotho), Swaziland, and the Transvaal highveld. It was traded into the rapidly expanding mining economy on the Witwatersrand, where African mineworkers smoked it in pipes often shared communally ^[3][4]. Mining companies and white administrators viewed dagga primarily as a labor-discipline problem, not a public health one — a framing that shaped early prohibition ^[4] Strong evidence.

East Africa. In what is now Kenya, Tanzania, and Uganda, bhang was used by some coastal Swahili communities and by certain Sufi orders, but European observers in the 1910s described it as less ubiquitous than in Southern Africa ^[2][5] Weak / limited. Colonial records from this decade are thin and sometimes conflate cannabis with other intoxicants.

Central and West Africa. Belgian and Portuguese sources mention diamba and liamba use in the Congo and Angola, often in work-song and recreational contexts ^[1]. In much of West Africa, by contrast, large-scale cannabis use is generally dated to after World War II, when returning soldiers reintroduced or popularized it ^[6] Strong evidence. The popular claim that cannabis was already widespread across West Africa in the 1910s is not well supported.

The 1911 Natal restriction and the road to prohibition

The Union of South Africa was formed in 1910. The following year, Natal passed restrictions on the sale and possession of dagga, one of the earliest cannabis-specific statutes in Sub-Saharan Africa ^[4][7] Strong evidence. The motivations were a mix of:

• Mining industry concerns about worker productivity and absenteeism;
• Racialized public-order anxieties from white settlers;
• Pressure from the Indian indentured labor administration, which had already restricted ganja under colonial Indian precedent ^[4].

In 1913 the Union government's Native Affairs Department began collecting reports on dagga among African workers ^[4]. These reports were uneven in quality but became the documentary basis for the 1922 nationwide restriction and South Africa's 1923 request that cannabis be added to the international drug control agenda under the League of Nations — a request that ultimately shaped the 1925 Geneva Opium Convention ^[7][8] Strong evidence.

In other words: the international prohibition of cannabis has significant roots in 1910s Southern African colonial policy. This is well documented in the historical literature and is not folklore.

Myths and folklore about this period

Several claims about 1910s African cannabis culture circulate online and in pop-history books. They deserve scrutiny:

• "Dagga was a sacrament across all African cultures." Overstated. Ritual use is documented in specific contexts (e.g., some Sotho and Zulu practices, certain Central African groups), but cannabis was largely recreational, medicinal, or labor-related in most documented 1910s settings ^[1][3] Disputed.
• "Rastafarianism shaped African cannabis culture in the 1910s." Anachronistic. Rastafari did not emerge until the 1930s in Jamaica Strong evidence.
• "Colonial powers banned cannabis because it threatened cotton/hemp markets." No serious evidence supports this for Sub-Saharan Africa in the 1910s. The documented motivations were labor control, racial governance, and moral reform ^[4][7] Disputed.
• "Africans introduced cannabis smoking to the world." Partially true and frequently overstated. The water pipe and earth-pipe smoking methods documented among Khoisan and Bantu-speaking peoples are genuinely ancient and may predate widespread smoking elsewhere ^[1][3], but the global picture is complicated Weak / limited.

Sources, gaps, and how we know what we know

Most surviving 1910s documentation comes from colonial administrators, missionaries, and a small number of ethnographers — none of them neutral observers. African voices from this period are largely absent from the written record, though oral histories collected later (notably by Brian du Toit in the 1970s) preserve some memory of pre-prohibition practice ^[3].

What we can say with confidence: cannabis was widespread in Southern Africa, embedded in mining labor, and the target of the earliest statutory restrictions in the region during the 1910s. What we cannot say with confidence: precise prevalence figures, the full ritual significance in specific communities, or the exact dynamics of West and East African use during this decade. Anyone claiming certainty about those details is probably guessing.
