How Cannabis Reached the New World – the Four Introduction Routes

The Starting Point

Cannabis is not native to the Americas. Domestication lies in East Asia (Ren et al. 2021), and before the transatlantic introduction from the 16th century onward there is no documented use across the continent. Everything that today counts as Latin American Landraces sits on introduced founder stock. Three colonial and migratory movements carried the plant across the Atlantic; Colombia joins via a fourth, later route. These streams later mixed.

The Iberian Fibre-Hemp Route (from the 16th Century)

Spain and Portugal first brought cannabis as a fibre plant – cáñamo for rope, sails and clothing, the backbone of the seafaring empires.

In Mexico, Pedro Quadrado cultivated cannabis around 1530, by his own account the first in the Americas; the Crown ordered sowing in June 1545 (Campos 2012). Drug use developed later within Mexico. Because the plant received a Nahuatl name – pipiltzintzintli – it was long wrongly held to be indigenous. In Chile, fibre hemp for ship’s rigging is documented from 1545 – fibre, barely a drug type, and the oldest continuous fibre-hemp tradition in South America.

From this strand root the Mexican landraces – Acapulco Gold, Oaxacan, Sinaloa, Michoacán – in Spanish fibre hemp plus internal Mexican selection, not in the Indian Caribbean route.

The African Slave-Trade Route (16th to 19th Century)

Enslaved people from Central and Southwest Africa brought drug-type cannabis and its use-culture. The linguistic fingerprint is clearly Bantu, specifically Kimbundu: in Brazil the plant is fumo de Angola, and nearly all Brazilian cannabis terms – diamba, liamba, riamba, maconha – are of African origin. More on this under maconha origin.

Cannabis was established in Africa via Indian and intra-African trade routes long before European arrival; from there it reached the New World with the slave trade. The dating of the Brazilian introduction is a genuine dispute: part of the scholarship dates it to the mid-16th century (slave-trade thesis, Mott/Carlini), other surveys only to the early 19th century, where the hard documentary evidence falls – such as the Rio ban of 1830. To be carried as strongly supported but not seamless.

The Indian Indentured-Labour Route (19th Century)

After the abolition of slavery, Britain brought Indian indentured workers to the Caribbean. They carried ganja – a Sanskrit/Hindi word – and the narrow-leaf drug sativa (NLD).

Jamaica imported through licensed channels from the Bengal region in the 1850s/60s; the indenture window ran roughly from 1845 to 1917. Because the Indian ganja cultivars were narrow-leaved, the Jamaican landraces turned out sativa-leaning. Trinidad and Guyana, with even larger Indian populations, share the same NLD founder. The St. Vincent sativa hangs on the same network through a documented pre-1970s base from Colombia and Trinidad. A possible additional African Congo route into the Caribbean is documented as a coherent secondary trace but remains contested.

Colombia – the Special Case

Colombia connects the routes rather than forming its own old root. Cannabis reached the country via the Caribbean coast through Panama in the early 20th century; the first recreational use arose in the 1920s/30s in the Atlantic ports Barranquilla and Santa Marta (Sáenz Rovner 2007).

The sativa fame followed only with the US demand boom: the Bonanza Marimbera from the mid-1970s to the mid-1980s in the Sierra Nevada de Santa Marta and the Guajira, shipped via the established coastal and banana routes (Britto 2020). US buyers did not drive the innovation – local sectors experimented with local crops and foreign seed and developed Santa Marta Gold from them. Colombian Gold, Santa Marta Gold and Punto Rojo thus hang on the same Caribbean introduction network as Jamaica and St. Vincent.

The Late Mixing

From the 1960s/70s, smugglers brought further genetics – Thai among them – into Colombia. Even the lines traded as “pure” received later gene flow; a genetic-test suspicion sees Colombian Gold as partly Thai-related. That closeness may equally stem from the shared South and East Asian ancestral gene pool (Ren et al. 2021) rather than from late gene flow – a genetic test alone does not separate the two (details under Colombian Landraces). The notion of eternally untouched pure lines must therefore be qualified. Via the Colombian Gold share this strand feeds Skunk#1 and the Original Haze.

Why This Matters

The common denominator of all four routes: introduced stock, regionally selected across the 20th century. The origin question is not “native or not” but which route, which adaptation, which selection. Whoever knows the routes reads every Latin American landrace more precisely – and separates documented genealogy from marketing folklore.
