Research shows marijuana hazards

New research suggests that marijuana use raises an adult’s risk of stroke and heart failure.

The study couldn’t prove cause-and-effect, but the researchers said they tried to account for other heart risk factors.

“Even when we corrected for known risk factors, we still found a higher rate of both stroke and heart failure in these patients,” explained lead researcher Dr Aditi Kalla, a cardiologist at Einstein Medical Center in Philadelphia.

“That leads us to believe that there is something else going on besides just obesity or diet-related cardiovascular side effects,” Kalla said in a news release from the American College of Cardiology (ACC). 

Her team is slated to present its findings tomorrow at the ACC’s annual meeting, in Washington, DC.

In the study, Kalla’s group looked at 20 million health records of patients aged 18 to 55 who were discharged from one of more than a thousand hospitals across the United States in 2009 and 2010.

Of those patients, 1.5 per cent said they’d used marijuana.

Such use was associated with a much higher risk for stroke, heart failure, coronary artery disease and sudden cardiac death. Pot use was also tied to common heart disease risk factors such as obesity, high blood pressure, smoking and drinking, the researchers said.

After adjusting for those risk factors, the researchers concluded that marijuana use was independently associated with a 26 per cent increased risk of stroke and a 10 percent increased risk of heart failure.

“More research will be needed to understand the [reasons] behind this effect,” Kalla said.

Not everyone agreed the findings are cause for alarm, however.

Paul Armentaro is deputy director of NORML, a marijuana advocacy group. He called the increase in heart risk, “a relatively nominal one,” and said the study “is inconsistent with the findings of several other longitudinal studies finding that those who consume cannabis, but not tobacco, suffer no greater likelihood of adverse events compared to those with no history of use.”

NORML agrees that certain groups – adolescents, pregnant or nursing mothers, people with a history of psychiatric illness, or those with a prior history of heart disease – may want to avoid marijuana due to the potential effects on health.

But others may want to talk the issue over with their doctors.

“As with any medication, patients should consult thoroughly with their physician before deciding whether the medical use of cannabis is safe and appropriate,” Armentaro said.

Study author Kalla noted that medical or recreational marijuana use is now legal in more than half of US states, so a better understanding of its health effects is needed.

“Like all other drugs, whether they’re prescribed or not prescribed, we want to know the effects and side effects of this drug,” Kalla said. “It’s important for physicians to know these effects so we can better educate patients, such as those who are inquiring about the safety of cannabis or even asking for a prescription for cannabis.”

Two heart specialists agreed.

The new study “suggests that marijuana may not be as safe as proponents for its legalization claim,” said Dr. Andrew Rogove, who directs stroke care at Southside Hospital in Bay Shore, N.Y. He believes that “further studies need to be performed to elucidate how marijuana use can increase risk for stroke and heart failure and if any particular way that it is used confers a higher risk.”

Dr Shazia Alam directs inpatient stroke services at Winthrop-University Hospital, in Mineola, New York. She believes there’s a growing number of patients of all ages with a history of marijuana use.

“As more of our patients will be on marijuana in the near future given the legalization trend, this study reminds us how important it is to ask about marijuana use early on and inform them of any potential consequences,” she said.

“Moreover, we have been seeing increased strokes in the younger population, therefore routinely inquiring about marijuana use may become an integral part in stroke prevention,” Alam added.

Because these findings are to be presented at a medical meeting, they should be considered preliminary until published in a peer-reviewed journal.

    Yawns. Cigarettes and alcohol legal and they can potentially harm your body and let’s not even talk about the social effect of substance. The fact is that smoking anything is bad for your health. Marijuana tea for example would cause a heart attach? Caribbean governments lack political gut to legalize marijuana but then again the new party BIM in Barbados made that promise. UWI should be leading research in this area. Not only would we be able to help alot of cancer patients and avoid chemo but we can export Marijuana for medicinal use. We are sitting on treasure and not fully aware of it.

      If this was a new vaccine …. persons would be flocking to hail the researchers for doing such good work in finding that this vaccine leads to such critical risks. Not saying that marijuana doesn’t have it’s benefits but like anything there are risks as well and now thats it’s in the public domain more than before, it will be test more than before.

      I specifically mentioned UWI and not cave hill. Our pm is the current chairman of caricom. If he had political will he could easily consult his legal advisers on what steps he can take to commission research. At least start with a national debate. We spent half a million on a commission just to move Mr Broomes from Alexandra school.

    Everything only in moderation. Remember when TV ads from the 1950s-1960s used to say smoking tobacco was very healthy too and you could even ‘spark up’ on planes and canteens? Give it several decades they’ll find out the problems with smoking weed too.

    Who is going to pick up the pieces, when we have lots of people wondering around not knowing what day it is ..
    Why is it that important to black people, at any costs as must have dont matter what……………………..

    • Jennifer March 18, 2017 at 3:03 pm

      jrsmith – “Who will pick up the pieces” – the gutters, just like the drunkards. And the hospitals with the people on CPAP and the ones with COPD. The thing in this no more dangerous that steeping mango leaf, soursop leaf or hibiscus in a tea cup.
      There is also another way to look at this – There was no benefits of marijuana mentioned and why. The white race currently control and monopolize the tobacco and alcohol industry making billions and killing people too. They want a monopoly of the marijuana thing too.

    There is a lot of strategies and tricks in the trade in this $hit. I remember growing up as a child when my great granny would make coconut oil for cooking, our hair, skin etc. Then the “EXPERTS” got their SPONGE and started with the brainwashing and lies and told you that coconut oil was the worst thing in the world for you and that it was causing the hardening of arteries, strokes and HTN. Now that these same experts have a grip on the production of the same coconut oil they are putting the same coconut oil and its milk into cooking oils (Which you cannot buy for your salads or stir fry’s). Into shampoos, vitamins, conditioners etc. It is an all for me and none for you game. These products are now very very expensive. Good thing I make my own oil and my kitchen is always smelling divine with my stir fry’s.

    Didn’t anyone notice that only 1.5% of the patients reported choosing to enjoy cannabis? In the US the latest numbers say that it’s between 13 and 14% of adults make that choice. A spread that wide renders this “science” nothing more that results to order “research.”

      Mark Gibbs, those plants (coca, poppy) are altered to make illegal Street drugs. Marijuana is not altered. The oils which are extracted are all natural. When it is smoked it is natural.

      My brother coca is what doctor does to save lives. You need to go on YouTube and see how man take the cocoa leaves and turn it into cocaine. You missing my point. Marijuana is not a man made thing. Alcohol is a man made. But I know for sure that you drinking it and Alcohol killed more people than marijuana.You not talking about alcohol because it is a white man business. Marijuana have a lot of different purposes. It cure a lot of diseases in case you did not know. Man miss used marijuana .

      Angus Benn March 19, 2017 at 5:56 am

      God made sugar cane also. And man turn it in rum and you drinking it.why you ain’t talk about alcohol where people getting killed every day. Scientists have shown that marijuana have a lot of different used. Man tells lie for years and have people like you brain wash.not because I know better. You need to do some research on marijuana. You will only know the use of marijuana if something was to happens to you.

      • Jennifer March 19, 2017 at 7:53 am

        Angus – And the white man (money god) controlling the sugar cane, rum, tobacco, alcohol etc. They only want a full grip on this marijuana too.

      Angus Benn March 19, 2017 at 6:03 am

      My brother use your own common sense. Do you know how much people using marijuana on a daily basis. You need to find out. If marijuana was so bad it would kill half the world population already.

      It comes in ointment and spray to be used on joints for arthritis pain. There is also editable oil to be added to foods. There are many marijuana based products which has been proven to be beneficial for insomnia, pain caused by auto inflammatory illnesses just to name a few. Learn about the CBD and THC beniffits and it’s differences. Marijuana does not have to be smoked, nor does it have to be used as a high. It all depends on the purposes it is being used for.

  25. Ralf March 19, 2017 at 6:57 am

    @Jennifer Yes I remember growing up hearing that coconut oil was so bad for you and the harmful effects it had on the body and we were encouraged to buy olive oil. Now coconut oil has all of these health benefits after the industry has changed hands. The same thing is happening with the marijuana issue.

    @jrsmith – we know that too. Them BIG BIRDS FEATHERS PRETTY, AND THEY HAVE HIGH FLYING CAPABILITIES. The black man is the jail bait and alligator bait just as before. You don”t see their weaponry, they got guns now that can sense heat and pick you out from under the sea and all. But we gine soon see who weapons better. Taking time ain’t laziness.
