Cannabis is thought of as having originated in Central Asia, from where it was spread by human hands to all
the corners of the world. There are 2 types of cannabis available for today’s consumers: Indicas and
Sativas. Cannabis Sativa was first classified in 1753 by a Swedish botanist Carl Linnaeus. 30 years later, a
French biologist named Jean-Baptiste Lamarck came along and classified a second (and last) species of the
plant – the Cannabis Indica. As one of the oldest crops known to man, Cannabis has been cultivated for
thousands of years. Documents dating back to 2900 B.C. describe how humans have used it for consumption,
religious ceremony, medicine, and other purposes.
Today, there are thousands of strains of Cannabis, which have been selectively bread for their diverse
effects. From THC and CBD concentrations to tastes and smells, growers have mixed and matched the strains to
derive the optimal genetic combinations to suit their pallets, achieve various psychoactive effects and
treat medical conditions. The landrace strains (Afghani, Thai, and Hawaiian to name a few), or the original
strains of pure and unmolested genetics are the forefathers of all the modern varieties, were named after
the regions of the world from where they came. Unfortunately, landrace strains are virtually bread out of
existence by now and most of what we have today are hybrid descendants of the original plants. Because the
climate, soil, fertilization, and even time of harvest can impact the chemical makeup of a plant, it is
thought that the landrace varieties carried superior genetics due to their natural adaptation to local
conditions over time.
Indica and Sativa strains are known for having unique properties. Sativas are recognized to be stimulating,
characterized by their cerebrally uplifting effects. Indicas on the other hand are known for their sedative
properties and have a calming, full-body effect. When mixed together, growers found a way to combine their
inherent properties to bring out the best of both worlds in a single strain, referred to as a "hybrid."

Originating in warmer areas closer to the equator, Sativa strains are recognized to be stimulating,
characterized by their cerebrally uplifting effects. Great for being active or social, sativa
effects are often referred to as making users "high", characterized primarily by an invigorated
Having evolved in the colder climates of Central Asia, Indicas are known for their sedative
properties and have a calming, full-body effects. Having a higher THC content, indicas are often
capable of producing a strong and sometimes overpowering buzz that is often referred to as being
By crossing various strains in countless permutations, growers found a way to combine the inherent
properties of indicas and sativas to bring out the best of both worlds in a single strain, which
came to be referred to as a "hybrid".
