Yesterday I posted the results of a study that found an increased risk of accidental and intentional death among women and young people with alcohol use disorders.

Rick Nauert reports on PsychCentral about a study by investigators from Northwestern University concerning the adverse impact of teens’ daily marijuana smoking on the shape and function of the hippocampus, a brain structure that plays a key role in the preservation of long-term memories.
“Our study provides definitive evidence that in heavy cannabis users, there is a detectable deficit of striatal dopamine release using an amphetamine challenge,” said Dr Weinstein. “Within the striatum, the subdivisions seem to have a different pattern, in contrast to reports of other substance abuse. And our exploratory analysis suggests that the deficits we are seeing in dopamine release in the striatum have a functional significance — that lower dopamine release is associated with lower working memory and learning performance.”
