A new study published in the journal Neuroscience finds that rats given regular doses of amphetamines during adolescence have brain and behavioral changes in adulthood. When translated into humans, this study suggests that young people using amphetamines may have changes in memory and attention well into their thirties.
“Along with other studies, this shows pretty clear evidence that drug use during adolescence, a time when the brain is still developing, has extremely long-lasting consequences that go far beyond the last drug exposure,” said University of Illinois psychology professor Joshua Gulley, who led the new research.
