Cannabis, the most controversy plant, but how informed we are about? Did you know that is considered among the oldest plants cultivated by humanity? About 12,000 years ago in areas of southern Siberia and Mongolia. Than is spread in China, Chorea, Middle Asia and Europe. This spread has happened thousands of years ago. Unlike in America it is widespread in the 1900s.

 There are 3 types of plant species cannabis: sativa, Indian and ruderalis. These three types differ in morphology, latitude, effects and symptoms to which can be used.

Cannabis sativa plant is thinner and longer, it grows in 0-30 degrees latitude. Its effects are enthusiasm, creativity and cerebral-focal effects. It can be used against depression, fatigue, and mood disorders.

Cannabis indiana is wider and shorter, increase in latitude 30-50 degrees. Its effects are relaxing the entire body. It can be used against anxiety, insomnia, muscle pain and muscular spasms.

Cannabis ruderalis is a widespread form much later. It grows in harsh conditions in latitudes up to 50 degrees in the areas of Russia and China. Is auto flower. This means that there is no need for the care of the growers. Its effects are very small and that is why it is not used for commercial reasons but if it crosses the type sativa or Indian take their characteristics while maintaining the virtue of auto flower.Canabis

What prohibit this plant is the presence of THC. Delta-9-Tetrahydrocannabinol, the psychoactive substance first discovered in 1964 by Israeli scientists Prof. And Dr. Raphael Mechoulam Yechiel Gaoni in Scientific Weizmann Institute. Our brain contains cannabinoid receptors in normal structure, which are located in areas of the brain associated with memory, thinking, pleasure, coordination and perception. THC binds to these receptors and activates them. This leads to a state of alert, changes in mood, alert sense of time, the mobility of the body, problem solving. While in the long term marijuana leads to increased heart rate, trouble breathing in children when mothers consumed during pregnancy, hallucinations, anxiety and depression.

Of course when we think of cannabis we think of marijuana which is the form of dried leaves of the cannabis plant. The study made in America in 2014 about 44% of last year of high school students use cannabis. It is consumed in the form of smoke, vapor or in various foods in solid condition. The most common approach is through cigarette smoke it, with tobacco or not inside.

According to the latest study conducted by the Brain Health Center, in the University of Texas early marijuana use causes changes in brain structure. They participated in the study adolescents who have started consuming her 16 years earlier. Specifically scanner took 42 heavy marijuana users. They were divided into two categories according to the average age of onset of use of it. One group of 20 individuals with early consumption in the average age of 13 years and another group of 22 individuals with early consumption at age 17. All participants were aged 21-50 years and reported an early start consuming marijuana in adolescence and its continuation in adults at least once a week. It was noted by the study is that the earlier launches consumption of marijuana the more increases the thickness of part cortical brain, the less contrast between the gray area and white and less complicated gyrification brain compared with users late marijuana. The study also noted a proportional relation between brain damage and the quantity of marijuana taken.

Debates about whether or not marijuana use, or for its legalization are still continuing. While these discussions continue perhaps it is time to give great importance to the new study about long-term effects that this substance in the brain of adolescents, the number of users who simply grows. This plant leaves used to the maximum to achieve the cure of several neurodegenerative diseases, but have struggled to maintain the health of those who will be the next generation!
