New research shows that heavy lifetime use of cannabis — more than 1,000 times — is associated with reduced activity in areas of the brain involved in working memory. The study adds to existing research suggesting that frequent cannabis use may affect certain thinking skills.

A massive new study sheds light on how cannabis affects the brain, particularly during cognitive tasks. Researchers analyzed over 1,000 young adults and found that both heavy lifetime use and recent cannabis consumption significantly reduced brain activity during working memory tasks.

One of the largest studies to date found more frequent use of marijuana over time reduces the ability to remember key information necessary to be safe and successful.

Heavy cannabis use may negatively impact a person’s working memory, according to the largest study on this subject to date.

A new study from the University of Colorado Anschutz Medical Campus suggests that heavy cannabis use negatively affects working memory.

Cannabis use can significantly impact the part of the brain responsible for following instructions, responding during conversations, or remembering a question long enough to answer it. This type of cognitive function is a form of short-term memory called working memory.

A recent study shows that regular marijuana use can negatively affect working memory, which could impact decision-making, work performance and social interactions.

A new study found that people who use marijuana frequently could suffer from impaired working memory, the short-term memory used for daily tasks.
