Early Substance Use Linked to Brain Structure Differences in Teens Featured Neuroscience December 30, 2024 Summary : A study of nearly 10,000 adolescents found that those who initiated substance use before age 15 exhibited distinct differences in brain structures compared to their peers . Many of these differences were present before substance use , suggesting a role in predisposing factors like genetics and . environment The research identified brain-wide and regional structural variations , particularly in the cortex , associated with early alcohol , nicotine , and cannabis use . While brain structure alone cannot predict substance use , these findings may help refine prevention strategies and models for understanding . addiction Key : Facts Early Onset : Indicators Adolescents
