Sativas are really indicas, ruderalises are really sativas, indicas are really afghanicas, and 2+2=5.
Dr. John McPartland reviewed his recent research and findings at the International Cannabinoid Research Society meeting in 2014. There he challenged the designations give to cannabis strains for decades. Generally, tall plants with narrow leaves are usually assigned to the sativa category, while plants that are shorter and stockier are known as indica plants, and incredibly shorter but more durable ones are ruderalis plants.
Sativas ordinarily provide more of an energetic “head high” as compared to indicas which produce a more laid-back “body high”. Ruderalis is rarely used recreationally or medically because of its low levels of THC, but its strains are similar to those of hemp making it a tough and long lasting plant. Cannabis ruderalis originates in Russia and was first classified by a Russian botanist by the name of D.E. Janischevsky in 1924 and the others were classified during the 1800’s.
But McPartland claims that sativas should be referred to as indica and indica should be called afghanica, while ruderalis should be known as sativa. His proposition totally does away with ruderalis and adds in afghanica, a new term. Confusing, right? There have been many people before him who have challenged the cannabis classification system, but not many people are persuaded enough to change their ways of identifying these marijuana yielding plants. Many people want to learn more about his position so McPartland plans to soon release his full analysis, research and data to support his claim in an accredited journal.
