I think this is making the assumption that temporally elevated HR and BP is bad.

Weed (as prescribed) gets me and many others moving and active.

There was a deliberate effort to demonize weed in the US as it's associated with mexicans, black people, and counterculture, and it's difficult to monetize if it's legal (anyone can just grow it).

Also, there are alternatives to smoking it: use a dry herb vaporizer with no tobacco and you avoid the vast majority of the negative health effects.

Did you brother have a Coronary Artery Calcium score scan?

No. This was about ten years ago. But not much has changed as I cannot get CAC score on Medicare even though they wanted to put me on statins. Cardiologist says I am fine. :/

They only cost about $100.

I find it interesting how many people come out of the wood work to make disparaging comments about people who use cannabis whenever the subject of cannabis use comes up on HN.

Having lived in a country where cannabis has been legal for about a decade now it's quaint seeing this kind of casual disrespect levelled by a stranger.

I wonder if this kind of mindset is still common here and people just don't vocalize it anymore, or if it's the kind of mentality that continued criminalization perpetuates.

Some commenters here talking about anxiety, but I think the bigger cause, which many people don't know, is that THC significantly increases your heart rate despite it's usual characterization as a depressant. If I recall correctly (big "if" considering the circumstances hah) my heart rate after smoking would go up by 10-20 BPM (from 65-70 to 80-90) while still feeling relaxed; ~~finding some numbers on this from a re…

There's more going on here than just the substance's effect. There's a mind body connection that an altered state can throw into disarray. Under the influence of cannabis, one may be a lot more aware of physical pain, dehydration, and so on. The key word is aware. Suddenly becoming aware of the fact that you are stressed out, you are carrying tension, can lead to something of a latent processing effect of some of the…

This. Street weed and medical cannabis are not the same thing.

I wonder about all the confounding effects. In my country (famous for cannabis to be easy to come by (for decades already), and I saw many smoke from age 16 up as I grew up in 90's, 00's). I have always felt that the heavy cannabis smokers had something to compensate; stress, unrest, impending depression, friction with parents. It was never the healthy sporty types with fulfilling relationships, good grades or a nice…

It was never the healthy sporty types with fulfilling relationships, good grades or a nice career that smoke cannabis heavily (like daily) ^^ many of those are boring people.

That is an opinion. I for one prefer talking to a happy, healthy mind, healthy body-type over someone with a life riddled with substance experiments. In fact, it was why I hardly talked to some of my family for a long time. Every weekend was the same, they were always angry and in the end they nearly killed themselves. I'm happy they got out of it and we have a much better relation now.

people just want their recreational drugs it's as stupid as smoking/vaping and not even black box warnings will get people to stop now if you need pain management I can respect that 100% but you need to investigate Palmitoylethanolamide and Geraniol as alternatives * https://news.ycombinator.com/item?id=48700498

> people just want their recreational drugs

Yes, people want to recreate, doing all kinds of activities with various levels of risk. They don't need to concern themselves with whether you can respect it.

Can you respect folks who are treating mental/emotional pain or just physical?

sure but you aren't going to help mental/emotional problems by getting stoned there are far better, legal supplements to treat that anyway, less expensive too dope activates AMPK in the brain/CNS and turns off AMPK in the body/heart it's an incredibly stupid thing to do to yourself (also why people get "the munchies") literally why it's called dope (before dope meant "cool")

With enough tolerance, you don't get stoned anymore. This is where you want to be, side-effects gone, just the good stuff left.

That's not really a fair standard by which to judge the study, abstract or not. The dosing mechanism information was not present in the underlying dataset available to them: > This retrospective cohort study utilized the TriNetX health research network, which aggregates deidentified electronic medical records from health care organizations worldwide. > 1) The cannabis-user group with cannabis use diagnoses (Internati…

Did they though? Not accounting for confounding factors like “other drugs” seems to indicate it’s not about the risks of cannabis use so much as the risks from all sources that the average cannabis user faces. Using only cannabis might have zero impact or even be beneficial based on this evidence (if you hypothesize that most of the negative outcomes were cannabis+cocaine users, for instance). Still good data, but I…

They didn't find that cannabis use leads to cardiovascular disease. They found a strong association between cannabis use and cardiovascular disease in a very large study. Correlation isn't causation. The study itself acknowledges that. That doesn't mean it's an invalid or useless study that didn't add to the body of scientific knowledge and evidence about the relationship between cannabis use and cardiovascular disease - I think we agree there. That's how science works. Observational studies do not definitively prove causality.

After reading the study, should we update our posterior on the hypothesis that cannabis use causes cardiovascular disease to nudge it in the direction that it does? Yes - that's just Bayes' theorem. Does the probability go to 95%+? No, of course not; I'm not claiming otherwise. It's still useful research.

Also, worth noting that MI risk spikes several-fold within the first hour after cannabis use (and that's not caused by cocaine).

Do you smoke?

If people are this concerned about heart health, they'd be wise to continue a zero-covid lifestyle into 2026 and beyond, since each re-infection (which vaccines don't prevent) increases the risk of severe health outcomes, including heart-related issues among lots of others. Yet I only see about .5-1% of the population in my area these days wearing any kind of mask/N95 respirator in public.

Doesn't this apply to colds and flus too?
