>> People who smoke marijuana are three times more likely to die of high blood pressure, scientists say. They drew their conclusions from a follow-up study of 1,200 people who took part in a large and ongoing health survey. They were asked if they'd ever used marijuana. The risk of death from hypertension went up with each year of drug use.
Researchers at Georgia State University said there were difficulties with assessing use since they couldn't be sure that people had smoked the drug continuously since they first tried it. But since marijuana's known to affect the cardiovascular system, the results made sense, they said. Several countries and US states have legalized or decriminalized the drug in recent years, partly because many see it as benign.
