FTA: "Those studies did not ask people how they used cannabis " such as via smoking, vaping, dabbing, edibles, tinctures or topicals. (Dabbing involves vaporizing concentrated cannabis and inhaling the vapor.) However, "based on epidemiological data, it is likely that cannabis was smoked in the vast majority of cases," Jouanjus said."

People who consumed edibles laced with tetrahydrocannabinol, or THC, showed signs of early cardiovascular disease similar to tobacco smokers.

"We found that vascular function was reduced by 42% in marijuana smokers and by 56% in THC-edible users compared to nonusers," Dr. Leila Mohammadi, an assistant researcher in cardiology at the University of California, San Francisco, told CNN in a prior interview.

None of the studies included in the new meta-analysis asked users about the potency of THC in the products they consume. Even if they had, that information would be quickly outdated, Silver said.

"The cannabis market is a moving target. It is getting more potent every day," she said.

"What's being sold to people today in California is 5 to 10 times stronger than what it was in the 1970s. Concentrates can be 99% pure THC. Vapes are over 80% THC."

If valid I wonder if there are specific cannabinoids that could be to blame? Does CBD have similar risks?

It really seems stupid to include "compared to the 70's" as if the majority can relate to getting a bag of dry crap that was crammed and transported across several states. My local dispensary currently offers fine starts for $25.
