The use of long -term cannabis in any form has been related to a higher risk of heart disease.
In a new study, UC San Francisco researchers determined that eating edible cannabis, such as gummies, has the same impact on the cardiovascular risk as smoking marijuana.
The risk derives from the reduced function of the blood vessel, according to the study, published in Jama Cardiology on May 28.
Heavy use of cannabis could mean this threat to the brain
The study included 55 people between the ages of 18 and 50 who were “out of health”.
The participants were divided into three groups: those who smoked marijuana, who ate edibles containing Thc (tetrahydrocannabinol) and those who did not use cannabis, according to a statement from the UCSF.

Cannabis users had been consuming the substance at least three times a week for at least one year.
On average, smokers had a habit for ten years, while those who consumed edible for five years, said the launch.
In September 2024, participants underwent tests to determine the operation of their blood vessels and if the cells that lined the blood vessels were affected.

It was found that all cannabis users had a “decrease in vascular function”, comparable to those who smoke tobacco.
Its function of the blood vessel was about half compared to those who did not use cannabis.
Researchers have been related to a higher risk of heart attack, high blood pressure and other cardiovascular conditions.

Participants who smoked marijuana also found that they had changes in their blood serum that damaged the cells that lined the blood vessels and lymphatic vessels, an effect that was not seen in those who ate edible cannabis.
Researchers said that while smoking marijuana and consumed edible, they both affect the vascular function, they are likely to do so for different reasons.

“Chronic cannabis smoking and ingestion were associated with endothelial dysfunction [impaired functioning of the endothelial cells lining the inside of blood vessels] Similar to those observed in tobacco smokers, although they are apparently produced by different mechanisms, “the researchers wrote.
“This study improves understanding of possible risks to vascular health related to cannabis use and provides more evidence than cannabis use is not benign.”

Dr. Bradley Serwer, a cardiologist and medical director of Maryland of VitalTollation, a naive health company that offers cardiovascular services and anesthesiology in hospitals in the country, said he was not surprised by the study’s conclusions.
“We have learned that chronic use of compounds that contain THC can have negative health consequences; this study only reaffirms those previous studies,” said Serwer, who was not involved in UCSF research, told Fox News Digital.

The study had some limitations.
“The variability in cannabis strains complicates standardization,” the researchers wrote. “The use of self -realized cannabis can introduce souvenir bias; thus participants were consulted at various points: in the online survey, in the eligibility interview and before each visit.”

It was also difficult to determine if the function of the blood vessel could also have been affected by life factors such as stress, caffeine and second -hand smoke exposure, they said.
Serwer said that this was a “very small” study of only 55 people, all living in the area of San Francisco Bay.
“The decision to use or avoid -must be taken with all the benefits and risks instead.”
“The study did not allow variability in the different strains of cannabis and used a self -reporting survey, which can be emphasized or exceeded,” Fox News Digital told.
“They sought physiological and non -extreme ends, such as heart attacks, stroke or death accidents. We must deduce that the physiological ends would lead to cardiovascular events.”

The cardiologist said that he agreed, however, with the conclusion that the use of cannabis is not “benign”.
“Chronic use has possible cardiovascular risks,” he warned. “There are therapeutic uses of cannabis and the decision to use or avoid -it must be taken with all the benefits and risks instead.”

“We have learned that chronic use of compounds that contain THC can have negative health consequences; this study only reaffirms those previous studies,” a cardiologist said. (Istock)
Serwer generally said he warns all his patients to avoid unnecessary heart risks.
“As clinics, we must weigh the benefits and risks of a drug/drug or intervention,” he said. “If the risks exceed the benefits, it should be avoided.”

The study was funded mainly by the National Institute of Drug Abuse; the California Department of Cannabis Control; the California tobacco disease program; the National Heart Institute, the Lung and the Blood; and the FDA Center for Tobacco Products.
