Jamaican Strain, or simply Jamaican, refers to the varieties of Sativa endemic to the island of Jamaica. Although these strains are generally considered to fit the definition of a landrace, cannabis did not actually exist in Jamaica until brought over by Indian indentured servants in the 1840s and 1850s when the British Empire ruled both Jamaica and India -- in fact, the word ganja, often used in Jamaica to refer to cannabis, is a variation of the Bengali word for hemp. The plant took quickly to Jamaica’s tropical climate and has since become renowned for its potent cerebral effects. Often sought out by tourists in Jamaica, true Jamaican Strain can be difficult to come by elsewhere.
