The consumption of cannabis in adolescence does not lead to changes structural of the brain in adulthood. This is confirmed by scientific research published in the magazine Drug and Alcohol Dependence.
Lo study, conducted by researchers at Arizona State University and the University of Pittsburgh, involved a thousand teenagers.
In the first phase, every year from the ages of 13 to 19, the children filled out some relationships on their cannabis use. Subsequently, depending on the consumption trajectory (from no use to daily use), were divided into four groups.
In the second phase, once they reached adulthood between 30 and 36 years, a subgroup of 181 participants underwent a series of brain tests to check for any differences in brain structure.
The tests analyzed 14 areas of interest in the brain, including six subcorticals, attesting that there is no difference in the structure of the adult brain in no subcortical or cortical region of interest.
"Consequently - concludes the study - the use of cannabis by adolescents cannot be associated to structural differences in the brain in adulthood"
