Study: Lifetime Cannabis Use Linked to Greater Cognitive Performance in Aging Populations
Aging adults with a history of cannabis use exhibit greater cognitive performance than those with no or little history of past use, according to researchers affiliated with the University of Colorado and Georgia Tech.
They assessed cognitive performance and brain volume in a nationally representative sample of more than 500,000 adults.
The researchers reported that greater lifetime cannabis use was positively associated with brain volume in regions rich in cannabinoid receptors and was also associated with better performance on cognitive tasks assessing learning, memory, processing speed, and task switching.
They concluded that these findings are important because they point to the possibility that cannabis could play a protective role in
aging, with implications for brain health later in life.
