A new study published in JAMA Network Open suggests that heavy cannabis use can negatively impact working memory. Researchers at the University of Colorado Anschutz Medical Campus found that 63% of heavy lifetime cannabis users showed reduced brain activity during a working memory task, while 68% of recent users also demonstrated a similar impact. The study, which involved over 1,000 young adults aged 22 to 36, used brain imaging technology to observe neural responses during cognitive tasks. Researchers noted a statistically significant effect on brain function during working memory tasks, particularly in areas associated with decision-making, memory, attention, and emotional processing.

Researchers said the study is one of the largest ever to be completed as they look into the effects of cannabis use on over 1,000 young adults aged 22 to 36 using brain imaging technology.Researchers studied the neural response of participants during a magnetic resonance imaging session. They then gave them seven cognitive tasks to complete.The tasks were meant to test working memory, reward, emotion, language, and motor skills.

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.

Medical Marijuana Users May Be As Prone to Addiction as Recreational Users, Study FindsA new study published in January 2023 suggests that individuals using cannabis for medical purposes might be equally or even more susceptible to developing cannabis use disorder (CUD) compared to recreational cannabis users. Researchers analyzed data from a federal survey and found that medical cannabis users exhibited similar rates of CUD as their recreational counterparts, particularly among younger men and women. The study highlights the importance of considering the potential for addiction when prescribing medical cannabis.
