Starting Age of Marijuana Use May Have Long-Term Effects on Brain Development, Says Study

Dallas, TX (Scicasts) —The age at which an adolescent begins using marijuana may affect typical brain development, according to researchers at the Center for BrainHealth at The University of Texas at Dallas. In a paper recently published in Developmental Cognitive Neuroscience, scientists describe how marijuana use, and the age at which use is initiated, may adversely alter brain structures that underlie higher order thinking. Findings show study participants who began using marijuana at the age of 16 or younger demonstrated brain variations that indicate arrested brain development in the prefrontal cortex, the part of the brain responsible for judgment, reasoning and complex thinking. Individuals who started using marijuana after age 16 showed the opposite effect and demonstrated signs of accelerated brain ageing. These are divergent patterns in overlapping areas of…
