Do you smoke?

Literally just wrote about that: https://news.ycombinator.com/item?id=48794178 > I've smoked cannabis daily for maybe 15 years [...] Visited a cardiologist like two months ago and have perfectly fine heart despite the smoking.

Many people have had cardiologists say they have perfectly fine hearts go on to have heart attacks months later. My brother was one of these people. He was going in for spinal surgery, cardio said his heart was fine. Two weeks after surgery he was short of breath. Turns out he needed a triple bypass.

And that was a physical change. Heart attacks happen because of electrocardiac issues as well.

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…

> stress, unrest, impending depression, friction with parents

Well, Id guess these are reasons for any case of substance missuse?

Exactly. Being unable to account for this covariate (tobacco use) pretty much invalidates this analysis. The odds ratio for tobacco use is basically the same (3x). Also, title needs a 2025.

This article refers to two studies. The retrospective study of 4.6 million people did account for tobacco use. > The findings are from a retrospective study of over 4.6 million people published in JACC Advances and a meta-analysis of 12 previously published studies being presented at the American College of Cardiology's Annual Scientific Session (ACC.25). > Kamel and his team conducted the retrospective study using d…

I know you can't judge a study by its abstract, but they don't even mention the dosing mechanism, it's just "cannabis use".

Wouldn't they also be potential causes that lead to worse heath outcomes that were not measured in the study?

Not really related, but the other thing I found out recently that cannabis can cause is the worst panic attack I have ever experienced: a DPDR (derealization / depersonalization) panic attack. I’ve had regular panic attacks before. I get one a year, roughly, where I get essentially heart attack symptoms. But this was something else. It felt like something was truly, irrevocably broken with my mind and I couldn’t even…

Anecdotally this isn't uncommon among heavy users, I've heard of similar things happen to a few people. You did the right thing stopping, where people really go off the deep end is when they don't listen to the warning signs and keep blazing.

I think weed should be legal and for the majority of people used in moderation it's going to be fine, but at the end of the day it's a psychoactive drug. It's probably not optimal to use it daily and in particular waking and baking every day is asking for trouble.

Also a case to be made that modern strains are worse. I fully believe that the risk of losing the plot is higher when you're smoking some lemon sherbet bubblegum flavours every day instead of old fashioned moroccan hash

For me, cannabis causes anxiety, and it’s pretty well established that anybody with anxiety or bipolar or schizophrenia should not be using cannabis because it can make these much worse. I don’t suffer anxiety anymore, but there’s plenty of scientific evidence about the relationship between anxiety and cannabis use.

That's a very blanket statement, lots of people are in fact prescribed low dose cannabis for anxiety.

6x sounds too clickbaity.

but sure, still lets make to account by other "legal" substances (alco, tobacco, cocaine, pharmaceutics and other "lifestyle choices" infecting cardiovascular system) and way they are consumed(smoked, ingested, pure or with say tobacco)

would love see data for a group who consumes cannabis by ingestion and especially not via smoking!

also- do they differ different thc/cbd grades used (high/low thc, "medical")?

im regards "research demonstrates something does this.." for many years alcohol was considered "healthier" over non consumption, just becauses non-drinkers were together with those of abstinent ex-alcholics.. thus average score was lower than for those who drunk minimal amounts and were considered "healthier".

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

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

> researchers were unable to account for several potential confounding factors including the duration and amount of cannabis use or the use of tobacco or other drugs. Personally I'd wager a bet it's the tobacco and/or smoking that is the harmful part, but it kind of dumbfounds me they failed to account for "details" like "duration and amount of cannabis use", that feels like a very vital thing to control for. Nothing…
