I read the articles before NY Times picked them up; it's paywalled.
Suppose the same can be said for alcohol and relaxation, if we see evidence of more heart attacks, it means the negative effect is bigger than the (hypothetical) positive.
THC is hypothesized to have direct effects on the vascular system that might lead to CVD, so none of these.
The same study did find that smoked marijuana induces the same changes in blood that smoking cigarettes do, and those changes lead to CVD, cancers, etc in tobacco smokers.
edit: This is what I'm thinking of: https://pubmed.ncbi.nlm.nih.gov/40434782/
Intuitively these effects would not be related to THC, but instead cannabigerol (CBG), which is known to have adrenergic effects.
