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.

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.

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.

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

A new study has revealed how both recent and lifetime cannabis use can affect cognitive function and working memory.

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

A study of over 1,000 young adults reveals that both recent and heavy lifetime cannabis use reduce brain activity in regions critical for working memory, including the prefrontal cortex and anterior insula.

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