Like avocados, apples, potatoes, and most other commercial crops, cannabis comes in a wide range of varietals, commonly called strains. Think Haas, McIntosh, Russet—only, you know, with weed. The oldest cannabis strains are collectively categorized as landraces, a term used to describe any genetically distinct varietal that’s indigenous to a specific geographic region, where it has—over a long period of time and isolation—adapted to the area’s climate and traditional cultivation techniques. Part of this process is natural acclimation, but local cannabis growers have also selectively bred these landraces over many generations, choosing for propagation individual plants that show desired traits, like drought resistance in an arid climate or mold resistance in a place with chilly nights and dense fog. Often these landrace cannabis strains are named at least in part for their region of origin: Think Panama Red, Maui Wowie, and Malawi Gold. Further back, according to most scholars, the cannabis species originated as a feral annual plant in Central Asia approximately 15,000 years ago, and from there spread worldwide along ancient trading routes, which means that all strains throughout history share a common ancestor. North America’s earliest pot smokers came up puffing on pure sativa landrace strains native to Mexico, the Caribbean, and points further south. 7 Cannabis Strains That Changed the Game
