A new study published in JAMA Network Open examines the impact of cannabis usage on brain function, particularly in areas involved in memory and decision-making. The study, led by researchers at the University of Colorado Anschutz Medical Campus, is the largest of its kind, examining over 1,000 young adults aged 22 to 36 using brain imaging and cognitive evaluations.
According to the findings, both recent and lifetime cannabis use can impair working memory, which is essential for everyday tasks, including following instructions, problem solving, and making informed decisions.
As cannabis use spreads, it is critical to understand the potential hazards and consequences on cognitive function. This study highlights the significance of mental stimulation and brain training in maintaining peak mental performance. Regardless of age, engaging in activities that challenge the brain can counteract cognitive decline and improve memory retention.
Key Takeaways
A new study found that cannabis use can impair working memory, but keeping the brain active through mental stimulation and brain training may counteract this effect.
- Cannabis use can reduce brain activity in areas involved in decision-making, attention, and emotional regulation.
- Engaging in activities that challenge the brain, such as puzzles or reading, can improve memory retention and cognitive resilience.
- Abstaining from cannabis for a lengthy period of time may result in partial recovery of cognitive function, but more studies are needed to determine the duration and extent of possible improvement.
A statistically significant link
The study discovered that 63% of heavy lifetime cannabis users and 68% of recent users had lower brain activity when undertaking a working memory task.
Working memory is essential for temporarily storing and retrieving information, such as recalling a shopping list or digesting instructions during a discussion. Reduced function in this area may cause challenges in daily living, including work performance, learning, and communication.
For years, clinicians, family and friends who knew heavy cannabis users understood that their memories were ‘shot’

Brain scans found that excessive cannabis usage had an influence on certain brain regions, such as the dorsolateral prefrontal cortex, dorsomedial prefrontal cortex, and anterior insula, all of which are involved in decision-making, attention, and emotional regulation.
While the study examined other cognitive processes like language processing and motor skills, only the reduction in working memory was statistically significant after thorough data correction. This underlines the significance of keeping the brain active at any age, as continued cognitive engagement might help offset any deficiencies.
The role of cognitive stimulation and brain exercises
One of the study’s primary findings is that cognitive activities and brain exercises may be good for people concerned about their memory performance. Other studies have found that mental activities, such as puzzles, reading, and strategic thinking, can enhance brain networks and promote cognitive resilience. While the study did not specifically investigate whether cognitive training may restore cannabis-related memory deterioration, earlier research indicates that a busy brain is more adaptive and capable of recovery.
Furthermore, the study raises an essential question: Can heavy cannabis users enhance their memory function if they quit? Although the long-term consequences are unknown, some study indicates that abstaining from cannabis for a lengthy period of time may result in partial recovery of cognitive function. However, the researchers emphasize that more studies are required to determine the duration and extent of possible improvement.
The benefits of keeping the brain active
The results emphasize the wider significance of maintaining brain activity at any age, regardless of cannabis use. For both young folks and older people hoping to maintain cognitive capacities, mental engagement is essential. Continuous learning, memory exercises, and problem-solving activities are some of the activities that can help preserve brain function and lower the risk of cognitive decline.
This study serves as a reminder that brain health should be a lifetime concern, even though more research is needed to fully understand cannabis-related memory impairment. Making mental fitness a priority can improve general well-being and cognitive lifespan, whether through organized cognitive training, social interaction, or lifestyle modifications.
Conclusion
Maintaining brain health is critical at any age, particularly as cannabis use increases. Cognitive stimulation and brain exercises can aid in maintaining memory and decision-making skills. Prioritizing mental fitness through lifelong learning and engagement improves cognitive resilience, lowers the likelihood of impairment, and promotes general well-being.
