The drug has becoming increasingly commonplace over the past several years — but researchers stress the need for more caution.

An increasing number of studies are showing that marijuana may not be so harmless after all.

In two new studies, to be presented later this month at the American Heart Association (AHA) Scientific Sessions 2023, researchers found that regular marijuana use increased the risk of heart attack, stroke or heart failure — even after factors like type 2 diabetes, high blood pressure and obesity were taken into account.

“Prior research shows links between marijuana use and cardiovascular disease like coronary artery disease, heart failure and atrial fibrillation, which is known to cause heart failure,” lead study author Yakubu Bene-Alhasan, M.D., MPH, a resident physician at Medstar Health in Baltimore, said in a statement. “Marijuana use isn’t without its health concerns, and our study provides more data linking its use to cardiovascular conditions.”

      Well now you’ve made me google. 🙂

      IIRC that’s a different problematic component.

      The component that causes popcorn lung is diacetyl. https://reason.org/backgrounder/debunking-the-myth-that-vaping-causes-popcorn-lung/

      I no longer vape, but when I did it wasn’t too hard to find sellers who would provide lab results or other certification that they did not use diacetyl in their flavorings.

      Your link also distinguishes between the two:

      vape-related injury concerning a teenage boy in Canada has recently gained the media’s attention as well. The 17-year-old boy vaped “intensively,” adding THC to his devices. He initially showed symptoms aligning with bronchiolitis (lung condition normally caused by a bacterial or viral infection), but many patients that have vape-related illnesses in the United States have experienced damage to the alveoli; this type of injury was not found. Instead, his case aligned more with an injury called “popcorn lung,” an ailment most commonly seen in factory workers of microwave popcorn plants nearly 20 years ago. This new vape-related case calls for further exploration into the toxicity of vape liquid, as the patient’s condition could have been caused by the THC added to the vaping devices, or the chemical that affected factory workers in the past - diacetyl. Diacetyl is present in many e-cigarette flavors [14]. The American Lung Association has called for the FDA to require that diacetyl and other hazardous chemicals be removed from e-cigarette cartridges.
