Cannabis is one of the first cultures practiced by humanity, a substance of daily use and multiple medicinal uses.
There are currently two forms of thought.
Those who argue that there are three distinct subspecies of cannabis and those who argue that cannabis has a single origin and that its composition varies according to the factors related to the territory in which it grows, that is, soil composition, climate and temperatures to which the plant is exposed.
In the post we deal with the first theory, describing the three different subspecies distinguishable in: Sativa, Indica and Ruderalis.
The specimens of this plant thrive in tropical climates, in conditions of heat, high precipitation and humidity. The Sativa reaches variable dimensions, ranging from 1.5 meters in height up to about 4-5 meters!
The THC concentration is low and is approximately 2%. For this reason the plant is used in the medical field to counter anxiety and depression problems or to alleviate the side effects of drug abstinence. They are also used as a stimulant of appetite and mood, in the treatment of eating disorders and to combat nausea caused by chemotherapy.
The effect of sativa cannabis is defined as "cerebral" as it may give effects of creative and artistic nature.
Indica cannabis is very resistant to both cold and drought and adapts to climates such as those in Nepal and Afghanistan, where they are grown.
The Indica are also excellent to be cultivated indoors, because of their reduced size shape (rarely over 3 meters) and their flowering times, clearly shorter than those of other varieties.
This plant is definitely among the varieties of marijuana that has higher levels of THC, and it can reach percentages even around 25%. Its effect is mainly relaxing: the use of this type of marijuana is recommended to promote sleep and help to calm stress due to an intense day of work.
As far as therapeutic use is concerned, Indica is used by those seeking relief from bone problems and migraines.
The Ruderalis cannabis, commonly known as Russian hemp, has the shape of a squat bush due to the harsh temperatures of the Russian steppe where it originates. Flowering does not depend directly on exposure to sunlight, but the plant blooms autonomously after a fixed period.
Ruderalis is characterized by a low THC content and it is not suitable for the production of marijuana, indeed it is mainly used to be combined with other plants to increase its strength, thanks to its small size and woody bark, which makes it more resistant than other types of cannabis.
