Central America and the Caribbean region have been another important chapter in the human-cannabis story. “Central America” for our purposes spans from Mexico through Panama, and we’ll also consider the Caribbean islands (like Jamaica) in this section, as their cannabis histories are tightly connected to the same migratory and colonial forces.
Mexico: Among all New World countries, Mexico has one of the longest and most influential cannabis traditions. Spanish colonial authorities introduced hemp to Mexico in the 16th century for fiber, but by the late 19th century, Mexican communities were also growing psychoactive cannabis, calling it “mariguana.” There are theories that the word marijuana itself may derive from Mexican Spanish (possibly from Chinese “ma ren hua” via immigrants, or from colloquial Mexican Spanish usage in the 1800s). Regardless of etymology, Mexico became a major source of cannabis for the United States in the early 20th century, and again in the 1960s–70s. The landraces in Mexico were mostly sativa in character, likely tracing back to a mix of influences. By the mid-20th century, distinct regional strains existed. The most famous Mexican landraces included Acapulco Gold, Oaxacan (Highland), and Michoacán (Brown). Acapulco Gold came from the Pacific coast near Acapulco and was renowned for shimmering golden-brown buds with a smooth smoke and uplifting high. Oaxacan was a highland sativa from southern Mexico’s Oaxaca state, often giving a very spiritual or psychedelic effect (some of the first “Haze” breeding stock in California reputedly included Oaxacan Gold). Michoacán, from west-central Mexico, was known for a reddish or brown appearance and potent resin; it had a slightly more sedative effect compared to other Mexican varieties. These landraces grew 8–12 feet tall, finishing in late autumn, and thrived in Mexico’s varied climates (Oaxaca’s high altitude gave one phenotype; Acapulco’s coastal tropics another).
Mexican farmers, often poor campesinos, selected their cannabis mainly by choosing seeds from plants that produced a sought-after effect or appearance. They typically grew fields of mixed plants, harvested, dried, and compressed the product into “bricks” for transport, with little removal of seeds. Thus, the selection pressure for sinsemilla was limited until later years when some growers adopted it for quality. Still, certain famous batches (like Acapulco Gold of the late 1960s) were reportedly seedless or low-seed and very potent, implying that some intentional cultivation improvements did occur.
Central American Isthmus: Moving south, countries like Guatemala, Panama, and Costa Rica also had cannabis cultivation, but less is documented. Panama, however, became legendary for Panama Red. Panama Red was a term for the high-quality reddish marijuana that came out of Panama in the 1960s. It was a pure sativa, known to produce a fast, intense euphoria (and sometimes anxiety in novices—it was that potent for the era). The strain name likely came from the red color of the stems or hairs and the country of origin. Panama Red became one of the bywords for strong weed in the 1970s U.S. counterculture. Its genetics possibly came from Colombian or other South American sativas that found ideal conditions in Panama’s climate, or it may have been a distinct introduction via the canal trade. By the late 1970s, however, Panama Red and other Central American landraces faded due to eradication campaigns and competition from Colombian and domestic US grows.
Jamaica and the Caribbean: Jamaica’s cannabis story is particularly rich culturally. African genetics may have appeared during the time of colonization upon the introduction of African slaves to the Caribbean. Cannabis (ganja) was further spread to Jamaica by East Indian indentured laborers between 1845 and the late 1800s. After Britain abolished slavery, it brought in workers from India to Jamaica’s plantations; these Indians carried cannabis seeds and the practice of smoking ganja. The plants thrived in Jamaica’s fertile soil. The Indian indica varieties (likely from Bengal or Uttar Pradesh regions originally) acclimated and interbred on the island, creating Jamaican landraces that were sativa-leaning (because Indian ganja itself was a narrow-leaf drug cultivar) and well-suited to the tropical latitude. Over the decades, Jamaicans of African descent also embraced ganja, and it became deeply embedded in folk medicine and later in the Rastafari spiritual movement (from the 1930s onward).
Jamaican landraces, often collectively referred to as Lamb’s Bread (or Lamb’s Breath), are typically vibrant green sativas with an upbeat, creative high. Bob Marley and other reggae icons frequently praised “Lamb’s Bread,” describing it as the finest herb giving inspiration and meditation clarity. This term may have originally referred to a particularly good phenotype (perhaps saying it was as sustaining as the biblical “bread of the lamb”), but now it effectively means authentic local Jamaican ganja. Jamaican strains, having Indian lineage, usually finish faster than pure equatorial strains—somewhere in 10–12 weeks of flowering—and can have a sweet, herbal flavor. Another Caribbean landrace of note is “Collie” or Brown Bud in Trinidad and St. Vincent, influenced by Indian arrivals and possibly later by interaction with Jamaican or South American weed. The word “collie” was even Jamaican slang for ganja, as heard in old reggae songs.
The human factor in the Caribbean was selective but not scientific. Ganja growers in Jamaica would often keep seeds from the best “mother” plants; over time, this created stabilized lines in certain regions (for example, Westmoreland in Jamaica was known for a specific type of potent ganja). One interesting development: because of pressure from law enforcement (like Jamaica’s Ganja Law of 1913 and later US-influenced eradication efforts), some Rastafarian growers took their operations into remote mountainous areas like the Blue Mountains or interior highlands. This inadvertently resulted in slight adaptation of those cannabis populations to higher elevation and poorer soils, possibly shaping the gene pool further (hardier, mold-resistant individuals being favored).
By the 1970s, both Mexico and Jamaica were major suppliers of cannabis to the U.S. and Canada. This era ended with intensified War on Drugs efforts: Mexico’s government sprayed cannabis fields with paraquat; Jamaica cracked down under US pressure; Colombia moved away from cannabis to other drugs. These enforcement campaigns, along with the emergence of domestic sinsemilla cultivation in North America, meant many landrace strains from Central America and the Caribbean were either lost, hybridized, or preserved only in the hands of collectors. For example, pure Acapulco Gold or Panama Red became increasingly scarce once those regions stopped mass producing. Similarly, Jamaican landraces faced competition from Amsterdam-bred hybrids that found their way into the island in the 1980s and 90s.
Thankfully, seed savers have managed to keep some of these lines alive. Today, one can still find seeds purporting to be pure Panama Red or Acapulco Gold (often reproduced by enthusiasts, not necessarily directly from the 60s batches but from line-bred descendants). In Jamaica, some Rastafarian and traditional farmers still grow the old ganja strains, although hybrids are also common now.
In essence, Central American and Caribbean landraces are the result of Old World cannabis meeting New World environments and local cultures. They complete the global circle of cannabis co-evolution: from Asia to Africa, Africa to the Americas, then blending and moving between the Americas themselves. They also illustrate how the late 20th-century prohibition era forced a hidden, selective breeding program, where smugglers and risk-taking farmers influenced which strains survived based on market demand and evading law enforcement. The famous names from this region (Acapulco Gold, Panama Red, Lamb’s Bread, etc.) remain ingrained in cannabis history as symbols of quality and potency, attesting to how human intervention (even under adversity) continued to shape cannabis genetics.
