Marijuana use holds three-fold blood pressure death risk: study

LONDON (Reuters) - 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 legalised marijuana and others are moving towards it. It is decriminalised 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.

 

The results showed marijuana users had a 3.42-times higher risk of death from hypertension than non-users, and a 1.04 greater risk for each year of use.

 

There was no link between marijuana use and dying from heart or cerebrovascular diseases such as strokes.

 

Yankey said were limitations in the way marijuana use was assessed -- including that researchers could not be sure whether people had used the drug continuously since they first tried it.

 

But she said the results chimed with plausible risks, since marijuana is known to affect the cardiovascular system.

 

"Marijuana stimulates the sympathetic nervous system, leading to increases in heart rate, blood pressure and oxygen demand," she said.

 

Experts not directly involved in the study said its findings would need to be replicated, but already raised concerns.

 

"Despite the widely held view that cannabis is benign, this research adds to previous work suggesting otherwise," said Ian Hamilton, a lecturer in mental health at Britain's York University.

Those financial advices on buying up shares of weed related businesses missed the point.

 

The money is in businesses related to funerals.

It is indeed scary stuff that you can have a very nasty reaction to, for frankly very little benefit/pleasure. 

 

And then when people drive cars it's even more scary.   (Assuming they can find their car)

You have obviously never smoked it, you're wrong on all counts.

If that is wrong on all counts, then it must affect different people in different ways. Many years ago I had a girlfriend who was a pothead.  I wasn't a user but I had a couple puffs from hers. I stopped a traffic light and when the guy behind me honked his horn, The light had turned green, I had no idea where I was at or which way to go.

We never used to put the roach in first; is it a filter?

You were a none user and had a couple of puffs? not really a sensible comparison don't you think? ''non user''.
