Study challenges negative cannabis stereotypes, claiming link to brain benefits
As cannabis has been rising in popularity among all ages, this type of study is important for understanding its long-term effects and the pros and cons of use, according to Matt Glowiak, Ph.D., chief addiction specialist with Recovered, an organization that provides information and resources for mental health and addiction treatment.

“Given the connection between cannabis use and larger brain volume, it is believed that it may help [older] individuals retain cognitive function that might otherwise naturally decline,” Chicago-based Glowiak, who was not involved in the study, told Fox News Digital.
“This is a huge benefit, but one we need to explore a bit further, ahead of encouraging those who would otherwise not consider integrating cannabis into their healthcare regimen.”
Limitations and caveats
As the study was observational in nature, it could not prove that cannabis use improves brain health — instead, it only showed an association, according to Dr. Marc Siegel, Fox News senior medical analyst, who was not involved in the study.
“The preponderance of previous evidence does not line up with improved cognitive function from chronic cannabis use,” Siegel told Fox News Digital. “This study is an outlier, and though it cannot be ignored, it is not justification for use.”

The study also relied on the UK Biobank, which offers a “large and rich dataset,” Guha said — but it is limited to the questions that were originally posed to the participants.
“In particular, we have only a broad measure of how many times someone has used cannabis over their lifetime,” she said. “We do not have access to details about how they used cannabis, such as whether they smoked or used edibles, the type or potency of cannabis, or when in their life they used most heavily.”

“Those details likely matter a great deal for understanding how cannabis affects the aging brain.”
Given these limitations, Guha suggests that the findings should be seen as an early indicator that cannabis use may be related to brain aging, “and as a starting point for more targeted research that can tease apart these relationships.”

“The takeaway is not that people should start using more cannabis based on these findings alone,” she emphasized. “While cannabis may have potential benefits in some contexts, a substantial body of research also documents important risks, underscoring that cannabis is neither completely beneficial nor completely harmful.”
The drug’s effects likely depend on factors such as age, dose, frequency, product composition and individual vulnerability, according to Guha.
“Given the widespread use and legalization of cannabis, it would be great to know that it is net-positive for brain health — however, this feels too good to be true, and too early to claim,” one expert said. (AP)
“As with any substance, individuals should consult with a healthcare provider before initiating use, particularly if they have a history of mental health concerns, as THC (the primary psychoactive component of cannabis) can exacerbate symptoms such as psychosis in vulnerable individuals,” she added.
Dr. Alex Dimitriu, who is double board-certified in psychiatry and sleep medicine and the founder of Menlo Park Psychiatry Sleep Medicine, reiterated that this study is an “outlier,” as most previous research has shown “detrimental effects” from cannabis use.

“Given the widespread use and legalization of cannabis, it would be great to know that it is net-positive for brain health — however, this feels too good to be true, and too early to claim,” he said. “I would advise proceeding with caution and moderation.”

Dimitriu agreed that more large-scale studies and review papers are needed to get a “clearer picture.”
“What this cannabis study shows is that there may be conflicting information, which warrants more investigation.”
