Students
who reported drinking alcohol occasionally/frequently and those who reported
using cannabis 10 or more times over the past 12 months had more than five
times and more than three the odds, respectively, of acquiring a traumatic
brain injury in the past 12 months than students who reported abstinence.
Brain
injuries among adolescents are particularly concerning because their brains are
still developing. There is growing evidence that people who have had one or
more concussions are at greater risk of future concussions, and evidence that
multiple brain injuries can result in lasting cognitive impairment, substance
use, mental health and physical health harms.
