Cannabis has been a hot-button matter for years. Some reward its health advantages, like ache and nervousness reduction, whereas others nonetheless label it the satan’s lettuce. And whereas most stoners have been busy celebrating 4/20, new analysis simply dropped a bombshell: a possible hyperlink between hashish use and dementia.
The cohort research, printed in the journal JAMA Neurology, contained information from greater than 6 million people aged 45 years or older with no historical past of dementia from 2008 to 2021.
Researchers analyzed that information to determine new dementia diagnoses amongst people who had required emergency division visits or hospitalizations because of common hashish use. This group was in comparison with three others: the final inhabitants, individuals who had care visits for any purpose, and people hospitalized for alcohol-related points.
“Long-term and heavy cannabis use has been associated with memory problems in midlife along with changes in brain structure associated with dementia,” says Dr. Daniel Myran, co-author, Canada Research Chair in Social Accountability on the University of Ottawa, and Associate Scientist at The Ottawa Hospital. “We set out to estimate the risk of being diagnosed with dementia in a group of people whose cannabis use resulted in a visit to the emergency room or required a hospitalization for treatment.”

Over the course of 13 years, 16,275 people 45 and older—60% of whom have been male—required an emergency or hospital go to because of hashish use. During the research interval, first-time acute care visits for hashish on this age group elevated greater than fivefold, rising from 6.9 to 37.6 per 100,000 individuals.
“Regular cannabis use might directly increase the risk of dementia through changes in brain structure,” co-author Dr. Colleen Webber said in a statement. “It’s also possible that regular cannabis use increases the risk of other established risk factors for dementia, including high blood pressure, head trauma and other injuries, and a higher risk for depression and social isolation.
Among individuals with cannabis-related medical care, around 5% were diagnosed with dementia within five years, and 19% within ten. This diagnosis rate was notably higher than that of people who were treated for other health issues during the study period. Regardless of other social and health-related factors, those who have cannabis-related hospital stays still have an elevated risk of developing dementia.
“While we collectively need more research to better understand potential risks of regular cannabis use on cognition and dementia, we hope these findings can inform discussion between patients and healthcare providers,” says Myran.
