The best outbreak may be to break your heart.
Although many North -Americans believe that daily marijuana use is safer than tobacco, a new study suggests that it could increase the risk of some severe cardiovascular problems.
Worse, gummies, teas and tinctures seem to be not to provide benefits to lighting when it is a critical factor for heart health.
High betting for the heart
The study of researchers at the University of California, San Francisco, participated in 55 residents of the healthy or regular smoking area of the bay.
None of the participants used nicotine and everyone consumed cannabis at least three times a week for a year or more. Smokers had an average of 10 years of chronic use; Edible users, five.
Researchers found that the function of blood vessels for regular cannabis users was about half that of non-users, and at the same time with tobacco smokers.
“We found that the vascular function was reduced by 42% in marijuana smokers and 56% in thc edible users compared to non -users,” Dr. Leila Mohammadi, lead author of the study, told CNN.
This surprised the co -author Dr. Matthew Springer. Groups like the American Heart Association had previously suggested that edibles could be less harmful to the heart.
“When I saw the result of the THC, I said to Leila:” Scientifically, this result of the THC is really interesting, but the guy causes the public health messaging, “he told Sfgate.
Above all, researchers found that only marijuana smokers had harmful changes in their blood serum, which adversely affected their endothelial cells.
These cells align the inside of the blood and lymphatic vessels and help regulate blood flow.
Springer said this could mean smoking marijuana offers a “double evil” of heart health damage.
The researchers emphasized that while their study indicates a strong association between chronic marijuana or the use of THC and vascular damage, it does not definitely demonstrate the link.
However, he adds evidence that chronic cannabis use could be bad news for the heart. A 2024 study found that on the day of marijuana daily the risk of heart attack increases by 25% and the risk of stroke by 42%.
“The public (and the medical field) must see cannabis and THC itself as products that are not without health risks,” Springer told Newsweek.
“The THC seems to have some beneficial effects, so there is a balance between the risk and the benefit that is best decided with both eyes open,” he added.
Research suggests that marijuana has the potential for relieving chronic pain and reducing muscle spasms and MS -related rigidity.
Cannabis products have also been shown to increase their appetite in patients with HIV/AIDS and cancer, and combat chimio nausea.
Other potential benefits are to relieve stress, relieve PTSD symptoms, and help sleep in some people.
Springer and Mohammadi ask for larger and older studies to reduce exactly how marijuana and THC affect the health of the heart and find out if there is a safe level of use.
The study comes, as north -Americans use marijuana regularly than ever.
Although alcohol is even more widely used in general, the use of heavy marijuana exceeded the heavy drink for the first time in 2022, according to Carnegie Mellon researchers.
That year, about 17.7 million Americans used cannabis daily or almost daily, compared to the 14.7 million they often drank. An impressive jump of 15 times has been marked in the chronic use of cannabis since 1992.
Marijuana remains illegally illegally, but 38 states and DC have legalized it for medical use. Of these, 24 states and DC have also erased the way for adults to use it recreational.
Recent legalization efforts have caused a boom in the use of cannabis. By 2024, 47% of North -Americans said they had tried marijuana at least once, up to 34% in 1999, according to Gallup Poling.
