In a new study, researchers at UC San Francisco determined that eating edible cannabis, such as gummies, has the same impact on cardiovascular risk as smoking marijuana. The risk stems from reduced blood vessel function, according to the study, which was published in JAMA Cardiology on May 28.

The researchers noted that while smoking marijuana and consuming edibles both affect vascular function, they likely do so for different reasons. "This study enhances the understanding of the potential risks to vascular health linked to cannabis use and provides more evidence that cannabis use is not benign."
