Another suspect for the highly abnormal brain functioning has been found in the form of the most commonly used illegal substance, Marijuana, whose use at an early age may lower down intelligence quotient (IQ) levels.
According to a study conducted by Lawson Health Research Institute, in Ontario, Canada, shows that people who use the weed from an early age may cause abnormal brain functioning related to visuo-spatial processing, memory, self-referential activity and reward processing.
Interestingly, scientists found no evidence related to improvement in depressing systems after consuming the weed.
The use of marijuana did not correct the brain function deficits of depression, and in some regions made them worse.
The study further suggested that consumption of the weed from an early age may higher the risk of cognitive dysfunction and psychiatric illness, including depression, bipolar disorder and schizophrenia.
Moreover, it was found that depression was even more in marijuana users.
The results were published in the journal Acta Psychiatrica Scandinavica.
