So far, Springer and his colleagues have published research demonstrating that just this one minute of exposure to secondhand smoke makes it harder for the rats' arteries to expand and allow a healthy flow of blood."
With tobacco products, this effect lasts about 30 minutes, and then the arteries recover their normal function. But if it happens over and over as when a person is smoking cigarette after cigarette, for example the arterial walls can become permanently damaged, and that damage can cause blood clots, heart attack or stroke.
Springer demonstrated that, at least in rats, the same physiological effect occurs after inhaling secondhand smoke from marijuana. And, the arteries take 90 minutes to recover compared to the 30 minutes with cigarette smoke.

All smoke is not the same, the particles are different sizes. I heard from a doctor about 30 years ago that the particles in MJ smoke are much larger than cigarette smoke. The cilia in the lungs can push the particles out. With cigarette smoke the particles lodge between the cilia, and eventually kill it. He said that was why you don’t see the rates of cancer and lung disease in pot smokers that you do in cigarette smokers. Sounds plausible.

No, tobacco fine, marijuana evil. Stupid science man.
