One 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)
Correlation != causation. Especially when the study doesn't show a simple correlation like that either. At least not for heart attacks.

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.
Another 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.
Putting 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.
Vape 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.
You're mistaken, those studies are specifically about vape cartridges which contain various other substances, flavors, and additives. Dry herb vaporizing is when the plant matter itself is heated via convection until the various cannabinoids aerosolize.
And a tastier and more pleasant high, generally. I like the ones with an all-glass or metal air path, generally, though the storz and bickle products are well regarded.
"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."
Would 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).
Anecdotally, 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.
Not 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.
It'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.
>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.
It’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.
> 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.
I 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.

Inhaling smoke is just flat out not good for you.

Are't e-cigarettes tobacco products?

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.
