These cannabis strains are thought to have originated in the early 1990s in the United States, before Dutch growers developed and popularized them on a large scale. Each cannabis strain has a different concentration of the cannabinoids tetrahydrocannabinol (THC), cannabidiol (CBD) and other compounds. However, there are different types of Cannabis Sativa that appeared and originated in different parts of the world. Some of them include Acapulco Gold, originally from Mexico, and Panama Red, originally from Central America.
If the labels describing cannabis strains actually represent two distinct groups of cannabis, the differences should be reflected in chemical and genetic differences. Our study, published in Nature Plants, found that indica and sativa labels are largely meaningless. Today, native strains have been selectively bred and blended to create hybrid strains that have more THC, shorter growth times or higher yields. Different strains can survive in different conditions and, in general, marijuana is quite adaptable.
All of these strains are a cross of two or more varieties of marijuana, as are the vast majority of their parent strains. Your favorite hybrid strain probably comes from a long line of careful artificial selection, but it all started with one or more native strains. There is also more information than ever available free of charge through resources such as the Weedmaps strain finder, Wikileaf and Leafly if you want to fall into an online cannabis rabbit hole. However, long before there were strong, fast-growing hybrid strains that are popular in today's legal recreational states, there were those known as native strains.
In addition, improving the diversity and quality of strains in the future will require careful selection and benefit from knowledge of strains from the past.
