Moderate Cannabis Use May Protect the Aging Brain

Neuro Science reports: "Moderate Cannabis Use May Protect the Aging Brain"!
"New research has uncovered a surprising link between cannabis use and brain health in middle-aged and older adults. In a large-scale study involving over 26,000 participants from the UK Biobank, researchers found that lifetime cannabis use in adults ages 40 to 77 was generally associated with larger volumes in specific brain regions and superior cognitive function." Preserved Brain Volume: Cannabis users showed larger regional brain volumes in areas with high density of CB1 receptors, including the hippocampus, which is vital for memory and often shrinks with age and dementia. Cognitive Boost: Participants with a history of cannabis use performed better on tests measuring learning, memory, processing speed, attention, and executive function.
