New Study Links Cannabis Use to Memory Changes, Sparks Discussion Among Local Users
A new study is shedding light on how cannabis use may affect the brain, particularly when it comes to memory and attention.
Researchers at the University of Colorado Anschutz Medical Campus analyzed brain imaging data from more than 1,000 adults during memory-related tasks. The study found reduced brain activity associated with working memory processing among many recent and heavy lifetime cannabis users.
Dr. Josh Gowin, who led the research, said the goal was to better understand both the short-term and long-term effects of marijuana use on brain function.
Researchers noted that previous studies have linked cannabis use to an increased risk of psychosis and other cognitive concerns, while ongoing research continues to examine potential connections to dementia and other neurological conditions.
At Reefer Madness Dispensary and Lounge in Palm Springs, budtender Kobe said the findings are important but emphasized that different cannabis strains can produce different effects.
He says some strains are marketed toward focus and creativity, while others are intended for relaxation, social settings or sleep.
Despite the study's findings, Kobe says cannabis remains part of his creative process, particularly in his photography work, and believes consumers should educate themselves about products and use them responsibly.
Researchers say more studies are needed to better understand how cannabis affects the brain over time and whether some effects may be reversible.
