Marijuana Use Doubles Risk Of Stroke
Source: Medical News Today
The most popular illegal drug, marijuana, has been found to double the risk of stroke among young adults, according to findings revealed at The American Stroke Association's International Stroke Conference 2013.
The study, carried out in New Zealand, identified that marijuana smokers were more than twice as likely than healthy adults to have suffered an ischemic stroke and transient ischemic attack (TIA).
Lead investigator of the study, P. Alan Barber, Ph.D., M.D., said:
"This is the first case-controlled study to show a possible link to the increased risk of stroke from cannabis. Cannabis has been thought by the public to be a relatively safe, although illegal substance. This study shows this might not be the case; it may lead to stroke."

Gotta wonder if they'll be doing a study to determine the possibility of ganja smokers breaking out in hysterical laughter...or their developing pot-bellies from eating too many munchies.

(90,061 posts)It annoys the hell out of me when they misuse statistics as some sort of magical hand-waving for political purposes, the modern equivalent of : "God says so". It amounts to little more than dissembling and gossip. The health care industry is just riddled with it, and it has much to do with the low quality of our health care system, public services, and governance.

Moosepoop
(1,920 posts)8.1 percent of those who came up positive in the urine samples smoked cannabis. There was no difference in age or stroke mechanism between those who smoked marijuana and those who didn't.
So, if I'm reading this right, "almost 16%" of the 160 people had positive drug screens, and 8.1% of those positive screens were for pot.
This "study" is beyond worthless.
maxsolomon
(33,345 posts)16% of 160 is 25. 8.1% of 25 is 2. That # made it seem like that had to be a misstatement.
Moosepoop
(1,920 posts)so much as an attempt at obfuscation. I would not be surprised if only two of the 160 stroke patients actually tested positive for pot, and one of them was a tobacco smoker besides.
Even if ALL of the 160 people tested pot positive, the assertion by the lead researcher that it was the pot causing the strokes while ignoring the high prevalence of tobacco smoking and the use of alcohol and other drugs as well tells me that this "study" was done for the purpose of reaching an already decided upon conclusion. The data didn't fit the narrative, so the narration of the data has been massaged to make it seem as though it does, making the whole thing completely worthless.
Either this was really, really bad reporting of the results of a scientific study, or the results have been publicly announced this way for a reason. My hunch is the latter.

(30,884 posts)The study sample was 160 stroke victims in the participant group and 160 healthy adults in the comparison group.
The participant sample had twice the rate of cannabis detected as the comparison group.
http://www.webmd.com/stroke/news/20130206/smoking-pot-may-raise-stroke-risk-in-young-adults
As noted in the above link, this is not conclusive evidence but it does add to the body of observations that pot may elevate stroke risk.
Moosepoop
(1,920 posts)The fact that they weren't able to account for tobacco use in the control group, or discern the amount/frequency/length of tobacco use in the stroke patients still makes this study largely worthless, IMO. Even people involved in the study downplayed its significance.
Something else in the WebMD article makes me question relying on any conclusions from the study: There were 160 hospitalized patients in each group -- the stroke victim group, and the control group. They tested each group of 160 for marijuana and came up with twice the number of positives in the stroke group as in the control group. OK.
The control group consisted of people who were admitted for other, unknown internal medicine issues. How many of these admissions were planned ahead -- say, for surgery or treatment of various conditions? People who know in advance that they are going to be admitted into a hospital and will be having urine and/or blood testing done may be more likely to abstain from partaking in illegal substances, thus lowering the number of positive tests in that group. Stroke patients, on the other hand, did not plan on ending up in the hospital at all, and would more accurately reflect the true number of users.
There are just too many "off" things about this study for it be taken very seriously.
Gormy Cuss
(30,884 posts)That's one of the reasons the authors need to use softer language like may cause more strokes. Comparison groups are sometimes necessary because there's practical way and/or ethical way to randomly assign the study sample and observe the outcomes. In a proper experimental design with a participant and control group, these results would have much more weight.
The comparison group seems to be a reasonable one given the details in that article. I haven't seen the full study report though.

(2,322 posts)...As this was apparently a study only of smokers, it really shouldn't be saying marijuana use doubles chance of stroke. It really should be saying: smoking marijuana can double chance of strokes.
And while we're at it, how much were these subjects smoking?
I certainly think the study is valid--marijuana probably does put a person at risk from stroke--however, there's a big difference between daily, recreational users (just as with tobacco or alcohol) and a cancer patient who takes the occasional hit to deal with chemotherapy nausea. I'm think we need more details on this study before we can judge if marijuana is, across the board, likely to cause strokes or if it's just those who smoke it regularly who are in danger.

I have to admit that I didn't read the labels closely enough to determine whether the hemp content was seed or leaf, but now that you mention it, since one of its greatest assets is its protein profile, maybe that IS, like other nuts and seeds which are valuable for their proteins, the hemp seed.

Anything and everything other than recreational highs!
It's a rubber substitute! It cures acne! it makes a lovely decorative hedge fence! You can use it to give your schnauzer hair extensions!
It's like the plant is Jesus and all these people are fresh converts.
Fuck that. The point of legalization is to not get arrested while perusing a high. That's more than enough reason for it, too. Don't need to sanctify the shit.
tridim
(45,358 posts)It does shrink tumors however, as documented in peer reviewed studies. You know, actual science. Do you understand the implications of this scientific fact? IT SHRINKS TUMORS.
It's a plant with thousands of uses, but apparently you just don't care. You know what? That 'tude is a big part of why it's still illegal. Thanks for nothing.
Obviously the point of legalization is freedom. You'd understand that if you really read what people say about cannabis.
Scootaloo
(25,699 posts)because the billion other uses of the plant with a billion-and-one uses are largely irrelevant to the cause of legalization. There is not a single motherfucker out there who is thinking, "Oh boy, if pot is legal, I can finally grow my own twine!" Y'know what I mean?
In fact, harping on endlessly about all those uses aside from the one that people are most interested in ends up doing more harm than good because that's what perpetuates the idea that getting high is "bad." If even the advocates treat it like a taboo topic and are instead talking about making cannabis-based insulation? C'mon.
I'm aware that the plant has lots of uses. Most plants do. Most of what you can do with weed can be done with motherfucking okra, too (though there's a tradeoff; can't smoke okra, and buds don't thicken your gumbo) But really the question of legality isn't about pressing your own hempseed oil and making paper. It's about the plant's primary use; recreational highs.
And just as you grow tomatoes because you like eating a tomato, you should be free to grow weed because you want to smoke it. You don't need a billion other excuses - and that's just what they are, excuses - to advocate this. If you're just going to punk out and pretend that you're pro-legalization because you're really interested in what Pfizer can squeeze out of it, then you might as well sit it out.

And the part where they admit that all of them also drank and used unspecified 'other drugs'. So this is a study of tobacco smoking, alcohol drinking users of multiple drugs. Oh, and they also smoked pot!

Almost, except....they were all smokers of tobacco. According to my doctors, tobacco is a huge risk factor, enormous. One also mentioned that drinking doubles the risk of stroke. So apart from the enormous risk factors they had, they had no risk factors. Odd form of doublespeak being employed makes me think they were out to find a conclusion and found it.

(2,117 posts)This study is the strongest piece of evidence that associates cannabis with stroke. The evidence is almost conclusive, except for the fact that only one of the cannabis users didn't smoke tobacco as well.
However, Barber believes that it is cannabis and not the tobacco that is causing the increased risk of stroke.
maybe instead-
"There are no deaths from cannabis use. Anywhere. You can't find one," said Dr. Lester Grinspoon, professor emeritus at Harvard Medical School.
Believe it: In 10,000 years of known use of cannabis, there's never been a single death attributed to marijuana.
"I've heard you have to smoke something like 15,000 joints in 20 minutes to get a toxic amount of delta-9 tetrahydrocannibinol," said Dr. Paul Hornby, a biochemist and human pathologist who also happens to be one of the leading authorities on cannabis research. "I challenge anybody to do that."
Meanwhile, it's a fact that anyone can die from ingesting too much aspirin, or too much coffee, or too much wine. Marijuana, on the other hand, medical or not, is not only non-lethal, but likely beneficial. Several studies, some published as recently as a few months ago, have shown that marijuana can even be good for your health, and could help treat conditions better than the solutions being cooked up in the labs.
The late Dr. Tod Mikuriya, a former national administrator of the U.S. government's marijuana research programs, appeared in a film about the business of marijuana prohibition shortly before his 2007 death called "The Union." (The full movie is available on both Netflix and YouTube.)
"After dealing with about 10,000 patents in the last 15 years, I'd say about 200 different medical conditions respond favorably to cannabis," Mikuriya said.

Studies reveal that marijuana protects against brain damage from stroke, heart attacks, and nerve gas.
Researchers are investigating how cannabidiol and other antioxidants can reduce the severity of damage from "ischaemic strokes", in which blood vessels in the brain become blocked.
During ischaemic strokes, which make up 80% of all strokes, free radicals are released into the bloodstream. These harmful molecules are believed to cause stroke damage, such as paralysis and loss of speech and vision. Cannabidiol has potent anti-oxidant and anti-inflammatory properties, so it can neutralize free radicals and limit their damage.

Yet since prohibition no one has ever questioned, thankfully, whether your average citizen has the right to consume it as he or she pleases (with the obvious exceptions of DUIs etc). And we all know how well prohibition worked out *rolleyes*.
So alcohol consumption is perfectly fine, a substance known since antiquity to be addicting and life ruining if abused, but NOOOooooo we need STUDIES to flesh out all the PROS and CONS of cannabis use before even thinking of legalizing it.

(3,286 posts)...in my humble opinion.
Despite a high risk lifestyle that included a stressful occupation, several years of alcoholism, fifty years of tobacco use and unhealthy eating habits I can only surmise that the cannabis I've been using for 48 years is the only thing that has prevented a stroke.
I believe that STRESS is the number one cause of ALL illness. Cannabis alleviates stress.
It can also enlighten the consciousness by alleviating the fear of powerlessness in the face of medical propaganda. Somehow it makes the threat of catastrophic illness just another irrational paranoia to be forgotten when the buzz wears off.
Of course, if one wants to ignore the threats promulgated by the medical industry, you have to go All In.
