A new study published in JAMA Network Open suggests that regular marijuana use can negatively impact brain activity, particularly in areas associated with working memory. Researchers found that heavy lifetime cannabis users exhibited reduced brain activity during working memory tasks, correlating with poorer performance in retaining and using information.
use can negatively impact brain activity , resulting in reduced memory capabilities, according to information published Tuesday in the medical journal JAMA Network Open.suggested that regular use of marijuana is related to “short- and long-term brain function outcomes, especially during working memory tasks.” It’s the latest“Working memory is the ability to retain information for a short period of time and use it,” Joshua Gowin, the lead author of the research, told CNN.
“When you’re in the middle of a conversation with your boss, you need to remember what they said long enough to respond to it,” Gowinrevealed that “ 63% of heavy lifetime cannabis users exhibited reduced brain activity during a working memory task, while 68% of recent users also demonstrated a similar impact.” The results come from using brain imaging technology to analyze the effects of marijuana use on 1,000 participants between 22 and 36 years old.
Results from the study showed that those who used marijuana had a notable effect “on brain function during working memory tasks, meaning the observed impact is very unlikely to be due to random chance.” Additionally, these observations in the study were “unlikely to be due to random chance,”reported.
“In this study of young adults, lifetime history of heavy cannabis use was associated with lower brain activation during a working memory task,” read the conclusion of the study. “These findings identify negative outcomes associated with heavy lifetime cannabis use and working memory in healthy young adults that may be long lasting.”

Heavy Cannabis Use Linked to Reduced Brain Activity in Working Memory TasksA new study, the largest of its kind, reveals that heavy cannabis use is associated with reduced brain activity during working memory tasks, suggesting that the negative consequences of heavy cannabis use may be more significant than previously thought. Researchers studied around 1,000 young adults, using MRI to monitor brain activity. They found that 63% of heavy cannabis users (defined as those who had used cannabis over 1,000 times in their lifetime) demonstrated reduced brain activity during working memory tasks, leading to poorer performance. While the study cannot definitively prove causation, it highlights the potential cognitive impacts of heavy cannabis use.
