marijuanaThe frequent use of marijuana can have a negative effect on the brain in adolescence and young adulthood, including causing impaired memory and learning, as well as lowering the IQ. These findings were made during the debate, which was held during the conference of the American Psychological Association.

According to researchers, in 2012 the use of marijuana among young people has increased almost three times compared to 1993. In the age group 18 to 25 years, 31% reported that they smoked marijuana in the last month.

Scientists argue that the dependence of marijuana  is accompanied by a decline in IQ with 6 points.

Magnetic resonance examination of the brain showed that by dependence of marijuana in brain structure persistent changes were observed, particularly in the gray matter, which build the bodies of the nerve cells.

Crucial importance has the content of tetrakanabioid in marijuana. Scientists emphasize that a high content of tetrakanabioid can lead to depression, anxiety and psychosis. Unfortunately, users who start with a low dose, gradually increase it over time.

Experts are concerned about the following pattern: in those countries where the medical use of marijuana is permitted, its consumption as a psychoactive substance increases. The reason is that it ceases to be treated as something related to the risk.
