A new study says smoking pot could increase your risk of dying from high blood pressure.
But Business Insider says, like a lot of studies, this one comes with a few grains of salt.
They say the study doesn't know how often the subjects used pot, only that they had tried it.
Different strains of marijuana vary a lot and are of course mostly, if not completely, unregulated.
And there's no way to know what was in the pot.
But some say there is enough evidence to warrant more study of the drug's effect on the cardiovascular system, especially with recreational use being legalized in more and more places.
