Correlation != causation. Especially when the study doesn't show a simple correlation like that either. At least not for heart attacks.

> The multivariate survey‐adjusted logistic regression analysis of the entire sample did not reach a significant association between daily cannabis use and CHD (adjusted odds ratio [aOR], 1.16 [95% CI, 0.98–1.38]; P=0.09)

But there does seem to be one for strokes

> Among those who had never used tobacco cigarettes and had never used e‐cigarettes, cannabis use was not associated with CHD or MI but was associated with stroke (aOR, 2.24 [95% CI, 1.31–3.83]) versus tobacco‐adjusted odds in the whole sample (aOR, 1.42 [95% CI, 1.20–1.68])

Smoking anything increases your risk.

It seems reasonable that deep inhalation of any burnt substance should increase risk. The burnig of fields in South Asia, for example:

I think studies show the effect with cake and edibles too

That is something that while not surprising at least should need some study before you state it as a fact.
