People who smoke marijuana have a three times greater risk of dying from hypertension, or high blood pressure, than those who have never used the drug, scientists said on Wednesday.
The risk grows with every year of use, they said.
The findings, from a study of some 1,200 people, could have implications in the United States among other countries. Several states have legalized marijuana and others are moving toward it. It is decriminalized in a number of other countries.
