Study finds link between marijuana use and cardiovascular disease
- djbusby 3y agoOne thing that's nice about the changes in perception and tolerance of cannabis use is that now we can actually get some real studies on the thing. It was in the dark for so long there isn't really a lot of science about effectiveness for ThingA or ThingB and/or what the sode-effects are (eg: hyperemesis, etc)
- bluGill 3y agoThough in this case I wouldn't expect to need a study to guess a link exists. But only now can we even hint at what should be obvious.
- friend_and_foe 3y agoSmoking weed increases your risk of heart attack and stroke. That was obvious this whole time?
- holyhelldang 3y agoSmoking anything increases your risk.
- eyegor 3y agoCorrelation != causation. Especially when the study doesn't show a simple correlation like that either. At least not for heart attacks. > The multivariate survey‐adjusted logistic regression analysis of the entire sample did not reach a significant association between daily cannabis use and CHD (adjusted odds ratio [aOR], 1.16 [95% CI, 0.98–1.38]; P=0.09) But there does seem to be one for strokes > Among those who had never used tobacco cigarettes and had never used e‐cigarettes, cannabis use was not associated with CHD or MI but was associated with stroke (aOR, 2.24 [95% CI, 1.31–3.83]) versus tobacco‐adjusted odds in the whole sample (aOR, 1.42 [95% CI, 1.20–1.68]) Study https://www.ahajournals.org/doi/10.1161/JAHA.123.030178 https://www.ahajournals.org/doi/10.1161/JAHA.123.030178
- dsq 3y agoIt seems reasonable that deep inhalation of any burnt substance should increase risk. The burnig of fields in South Asia, for example: "Air pollution and cardiovascular health in South Asia: A comprehensive review" https://doi.org/10.1016/j.cpcardiol.2023.102199 https://doi.org/10.1016/j.cpcardiol.2023.102199
- dubeye 3y agoI think studies show the effect with cake and edibles too
- bluGill 3y agoThat is something that while not surprising at least should need some study before you state it as a fact.

- awesomeMilou 3y ago> Who knows how many lives are shortened by sugar and a million other everyday things? Nevermind other substances, how can someone oppose the legalization of Cannabis, yet be perfectly fine with alcohol remaining legal, despite the fact that regular consumption of alcohol also has a strong link to cardiovascular disease? Shocker! It's almost as if drug consumption is bad for your health.
- kayyyy 3y agoSugar? Alcohol? Nicotine? Oh but a 19 year old should get 20 years for an eighth I guess.... for their safety of course!
- whaleofatw2022 3y agoYeah since all the super strict laws on opiates have helped Ohio, right?

- hprotagonist 3y agoAnother wrinkle to the study is the route of cannabis use and how it may play a role in the link to cardiovascular disease. About 74 percent of cannabis users in the study reported smoking cannabis, which could potentially increase the risk of cardiovascular disease much the same way as tobacco cigarettes—a result of inhaling particulate matter into the lungs. It's unclear if edible cannabis products would weaken the association seen in the study. Inhaling smoke is just flat out not good for you.

- astrea 3y agoWhat's your feeling on dry-herb vaporizers?
- wredue 3y agoPutting things in your body that have no need to be there is generally “not good” for you. Vaping is not good for your lungs. There is little actual study on whether it’s worse than smoking, especially in the long term. I do agree that some vaporizer companies claim it is safe, and those companies are lying. I don’t personally care if you choose to vape (except indoors in public spaces, or in highly congested outdoor places), and support legal cannabis, but you also probably should be careful about many of the claims of “safety” these products are making. There’s little evidence to suggest they’re safe, and no long term study at all. Anecdotes of the chemicals you are coating your lungs in are not particularly great, though.
- awskinda 3y agoVape concentrates can be worse based on what is used during extraction/added for flavor, etc. I agree it’s worse than doing nothing, but I am curious if herb vaporizers end up being similar to edibles in harm levels. Especially herb grown in an environment with no pesticides, etc.

- helpfulmountain 3y agoI don't understand this: "In the new study, led by Abra Jeffers of Massachusetts General Hospital, researchers were able to do two additional analyses: one that looked at cardiovascular disease risk in people who use cannabis but had never used tobacco products and a second one that looked at people who used cannabis but had never used tobacco products or e-cigarettes. Without tobacco use, the higher odds of heart attack and stroke persisted for people who used cannabis. For those without tobacco or e-cigarette use, only the higher odds of stroke remained." Are't e-cigarettes tobacco products?
- russelg 3y agoWould love to know how the method of consumption affects this, since the study seems to be targeting smokers (i.e. combustion) the results seem to make sense. It would be interesting if they included people who don't smoke (edibles) and people who use dry herb vapes (mostly convection).
- bhaney 3y agoAnecdotally, I've been a heavy user of THC edibles for several years and my cardiovascular health has noticeably worsened in that time. My resting heart rate has been slowly increasing for a while and I'm experiencing more and more frequent heart palpitations. If they're related, I wouldn't be surprised if the effect was indirect. Part of me suspects it's just from a reduction in physical activity, which wouldn't be influenced much by the method of ingestion.
- dubeye 3y agoSame here. I have cvd now and gave it up
- crtified 3y agoNot that external data changes your anecdotal experience. But you should note that this study also contains the following claim: > The multivariate survey‐adjusted logistic regression analysis of the entire sample did not reach a significant association between daily cannabis use and CHD (adjusted odds ratio [aOR], 1.16 [95% CI, 0.98–1.38]; P=0.09) Which is only one point. But it does illustrate the potential complexity of the interaction, and that we are a long way from establishing a clear causal chain.
- crtified 3y agoIt's an interesting study, and I admit I don't have the statistical skills to understand many of the connotations. I do note though, in the study, that the important summary Table 1 shows percentages for heart attack ("myocardial infarction") as 3.6% (3.1–4.1) for daily cannabis users, 2.9% (2.6–3.3) for non-daily cannabis users, and 3.7% (3.6–3.8) for non-cannabis users. Other factors must be taken into account, then, to result in the study's final claim, because obviously, 3.7% is more than 3.6%. Other factors (also reflected in Table 1) such as obesity - 25.5% for daily cannabis users, 33.0% for non cannabis users - and diabetes - 6.1% for daily cannabis users, vs 11.2% for non cannabis users (!). But those other factors are not exactly negligible, in the bigger picture. Quiet the opposite, one must surmise. There also seems to be a good deal of self-reporting behind the study, which I must assume brings with it a lot of confounding factors such as the socioeconomics of diagnosis ("more affluent people are more likely to have an official diagnosis"). There does seem to be a lot going on here.

- Spastche 3y ago>and diabetes - 6.1% for daily cannabis users, vs 11.2% for non cannabis users (!). I feel like that should be looked into, especially since stoners are eating all sorts of unhealthy food in the first place, you think they'd have the higher rates. is getting ready to eat a pizza
- ta2234234242 3y agoI would also like to see the numbers compared to those that consume alcohol and not THC. These articles keep making THC sound as though it's the worse thing imaginable, but in reality, I believe it's probably better than alcohol overall.
- alphabettsy 3y agoIt’s mentioned, but it doesn’t appear they’re able to determine if the people using cannabis also have issues causing them to be more likely to use cannabis like insomnia that also cause heart disease or if they eat worse.
- astrea 3y agoI do find this part of the article interesting: > But, the researchers do note that many studies have linked the use of cannabis to chronic pain, insomnia, and anxiety—all of which have also been associated with cardiovascular disease. Aren't those all exactly things people take cannabis FOR? Almost makes me feel like there's a political agenda.
- denkmoon 3y agoI wonder if this comes from being more sedentary. Cannabis doesn't exactly lead you to wanting to go for a run. (cue all the responses saying how they love to go for a run after a joint) Would also like to see the impact of consumption method. I use a "dry herb" vape so I don't inhale combustion products, and there is effectively _zero_ literature on these vapes. If these results are replicated with a vape like that which I use, I think it would certainly influence my thoughts on continuing or cessation.
