Adults who have visited the hospital due to cannabis consumption could have a greater risk of developing dementia.
A new study by the Institute of Clinical Evaluation Sciences (CIE) found that people who had an emergency department to use cannabis had a 23% risk of a diagnosis of dementia within five years.
Hospitalized people had a risk of dementia much greater than 72%.

The study, published in Jama Neurology, analyzed Ontario health data, Canada, between 2008 and 2021, in more than six million people from 45 to 105 years.

The investigation found that 16,275 of these individuals had acute care due to cannabis consumption. Sixty percent of these individuals were men, according to a press release.

The annual rates of acute incidents increased five times between 45 and 64 years, and 26.7 times in people over 65 years.
People who received acute attention due to the use of cannabis retained a high risk of dementia compared to the total number of people who received attention, excluding cases due to alcohol.
“This does not mean that the use of cannabis causes dementia, but highlights a worrying association.”
The main author of the study Dr. Daniel Myran, scientist at ICES and assistant professor of Family Medicine at the University of Ottawa, commented on the findings of the study in an interview with Fox News Digital.

The high risk of dementia persisted equally after factors were considered, including pre -existing health conditions, the socioconic state and prior care of good substances or mental health conditions, according to the researcher.
“Due to the design of our study, it is important to keep in mind that it does not mean that the use of cannabis causes dementia, but highlights a worrying association,” he said.
The heavy use of cannabis could represent this threat to the brain
Myran mentioned his surprise in the “very large” increase with the time of people 45 years or older with a visit or hospitalization related to cannabis.
“It increased more than five times, from 353 in 2008 to 2,508 in 2021,” he said. “In adults 65 years of age or older, he gets up 27 times.”
“These trends seem to be capturing important changes in the use of cannabis and possible advertising effects.”

Cannabis consumption does not come “without damage”, although it is legal in many places, according to the researcher. (Istock)
The number of older adults with a visit or hospitalization that later recovered a diagnosis of dementia was “also surprisingly high,” he said, with 5% to five five years and 19% at 10 years.

A limitation for the study was that researchers lacked details on cannabis use patterns and other health behaviors, such as smoking.
“As a result, part of the increase in risk is likely to be a relationship with differentials in behaviors between the groups that we could take into account,” he said.

The use of cannabis is associated with the “deterioration of short -term memory and long -term changes in brain structure”, according to ICE. (Istock)
“We also only examine the risk of dementia for people whose use of cannabis led to an emergency or hospitalization visit: this is a small subset and of greater risk of all cannabis users and does not tell us about the potential risks,” Hi “Hey,” Hey, “Hey,” Hey “, Hegs.

As the consumption of medical and recreational cannabis is now legal in many areas, Myran Emhasized that it does not mean that it is “without damage.”
“Like alcohol and other substances, the use or use of regular cannabis for the use of cannabis or the use of cannabis or the products of greater resistance, they come with important risks,” he warned.

“Our findings join a growing research suggestion that regular cannabis use can have negative impacts on the health and memory of the brain.”
