This study has been getting major media coverage, but it is completely flawed. They considered someone who smoked pot once 20 years ago and someone who has smoked 5 joints a day for 20 years as the same! Bad science! Why is this study being covered everywhere, while recent studies showing cannabis use has no negative effects on IQ get ignored? Dana Larsen

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.
“Support for liberal marijuana use is partly due to claims that it is beneficial and possibly not harmful to health,” said Barbara Yankey, who co-led the research at the school of public health at Georgia State University in the United States.
“It is important to establish whether any health benefits outweigh the potential health, social and economic risks. If marijuana use is implicated in cardiovascular diseases and deaths, then it rests on the health community and policy makers to protect the public.”
Marijuana is also sometimes used for medicinal purposes, such as for glaucoma.
The study, published in the European Journal of Preventive Cardiology, was a retrospective follow-up study of 1,213 people aged 20 or above who had been involved in a large and ongoing National Health and Nutrition Examination Survey. In 2005–2006, they were asked if they had ever used marijuana.
For Yankey’s study, information on marijuana use was merged with mortality data in 2011 from the U.S. National Center for Health Statistics, and adjusted for confounding factors such as tobacco smoking and variables including sex, age and ethnicity.
The average duration of use among users of marijuana, or cannabis, was 11.5 years.
