Cumulative lifetime use of marijuana hurts cognitive function in middle age.
Today many portray marijuana use as harmless. With more and more states legalizing its use, many believe it has no long-term effects on memory or other areas of cognitive function. Researchers followed over 3000 individuals for 25 years. Current marijuana use was associated with worse verbal memory and processing speed along with lower executive function in middle age.
PositiveTip: It may seem relatively harmless, but the use of marijuana negatively impacts cognitive function years later.
