This isn't news and can be inferred from the direct and immediate impacts of Marijuana. It elevates blood pressure and heart rate, stimulates changes in blood hormones, causes vasoconstriction in some tissues and dilation in others.

Even video screening with quack doctors for "medical cards" routinely cautioned people with pre-existing cardiovascular issues against use.

People can debate how big these impacts are or if anyone should care, but I don't think it is reasonable to argue the null hypothesis here.

Jogging?

People should realize that smoke is always harmful and then do real studies on actual drugs if they want to know something about them. Maybe marijuana is protective, but like everything, not protective enough for smoke inhalation. Probably not but who can say with such counterproductive health associations.

(CNN also has such a headline, but seems to have contemplated the limits of these studies a little better:)

Yes, exercise can be a major trigger for cardiovascular events as well, almost stereotypically so. This depends on your health and risk factors. Similarly, getting high isn't the same as going jogging, even if they both elevate your heart rate. How they do it, and what else they do matters. Chemical stimulants aren't anequivalent substitute for cardiovascular exercise.

Smoke shouldn't really have anything to do with these findings. We're talking about heart disease and not lung cancer. Smoking cigarettes is a risk factor for heart disease, but that's not because it is smoke, it's about the chemically active compounds in cigarettes.

Heart challenges are always going to raise the short term risks, avoiding all heart challenges the long term.. It's naturally a complex field, but public health didn't respond well to the no challenges approach.

Here is wood smoke, which is one of the challenges you definitely don't want because it is smoke:
