Prenatal exposure to pot is associated with differences in the thickness of the brain, particularly in the frontal brain, in preadolescent children. This was a study done with MRIS. This was written by Hanan El Marroun, Department of Child and Adolescent Psychiatry, Erasmus University, Rotterdam, the Netherlands and published online June 15 in Biological Psychiatry.
Children aged 6 to 8 years were invited into the MRI component of the program and the mothers use of cannabis exposure during pregnancy was measured with maternal self-report asking questions for each each trimester of the pregnancy. 113 nonexposed children; 96 children whose mothers smoked only tobacco during pregnancy; and 54 children whose mothers were studied during the pregnancy.
When comparing exposed to non-exposed children, those exposed to cannabis had “thicker frontal cortices, specifically, a thicker superior frontal area of the left hemisphere… and a thicker frontal pole of the right hemisphere” This part of the brain, the prefrontal cortex, supports functions such as the ability to suppress responses and thoughts, attention, higher-order motor control, and working memory.
