I find the study to be a bit suspect.

It found marijuana users had almost a four times higher risk of death from hypertension than non-users but there was no link between marijuana use and dying from heart or cerebrovascular diseases such as strokes.

Hello?

That seems very odd. Hypertension (high blood pressure) is a major risk factor contributing to the development of heart disease and strokes. And those associations are extremely strong and common. So it is bizarre to see a huge set of dead patients who had high blood pressure but no heart disease or strokes events.

The other organ that can get hit in a lethal way by high blood pressure are the kidneys, but again, it would be very odd that in a large set of dead patients who had high blood pressure you would see only kidney and not brain or heart disease.

I am thinking repeat studies on larger sample sizes are needed.
