The number one controllable risk factor for stroke and heart attack is smoking. By far. Not diet, not exercise, smoking. A significant part of that is because nicotine will constrict blood vessels leading to hypertension[1], this leads to destruction of the surface of an artery, leading to atherosclerosis formation. One day the atherosclerotic plaque ruptures and then you see me. We once thought that atherosclerosis…

Does that mean that caffeine is a risk too? Doesn't it have similar effects to nicotine? (I drink a loooooot of coffee).

Really disappointed there’s no comments here. I scrolled this whole thread to see if anyone had talked about coffee.

It got me thinking because I know someone who never drank coffee in their life and lived a pretty full life nonetheless otherwise ... they’re over 100 as of recently and still self mobile, super active, sharp as a tack. She even had quite a few children.

I consume like 4-5 actual brewed coffees per day. Am I doomed?

I would be curious to compare this to smoking an actual cigarette to see if there is any difference. Inhaling any vapor/smoke that isn't meant for your lungs is going to cause damage and it would be neat to see a comparison between the two. Anecdotal story time: My grandfather who is currently 81, has been smoking since he was 12. He grew up in a very small town, and had 6 people in his graduating class other than hi…

If your 02 is 68%, or even 75%, you’re likely about to be put in a coffin. Patients with severe COPD/emphysema might have arterial oxygen levels in the mid to high 80s without supplemental oxygen

Sounds like it was more of a lung function test. Maybe 68% of a healthy adult? Who knows what metric or baseline.

sorry if this comment is against the spirit of the community (i don't think it is, but I have been blocked from posting in the past oblivious to the fact that I wasn't contributing anything meaningful), but that being said... am I the only one who isn't surprised that someone managed to find that if you introduce something into the body that isn't generally there, that there is obviously going to be an acute response…

sometimes i really wish that people would actually tell me why they downvote what I have to say, rather than just silently doing so and condemning me to the bottom of the comments. i can't really really do the revision part of performance, feedback, revision without any actual feedback of substance to inform me as to what it is that I did wrong in the first place.

> The number one controllable risk factor for stroke and heart attack is smoking Can you clarify? Do you mean smoking cigarettes? Or do you mean consuming nicotine? What about vaping? How about smoking marijuana?

There's an information imbalance so definitive claims can't be made about cannabis smoking in the way that they can be made about Tobacco smoking.

Imsuspect marijuana smoking is just as harmful. The bulk of the trouble from tobacco is from the smoke. And if you look at the health effects of air pollution, they’re very similar to smoking: respiratory infections, heart disease, COPD, stroke and lung cancer

Inhaling any burning thing is quite bad for the human organism.

Smoking is one of the leading risk factors for cardiovascular disease: agreed It starts earlier than a lot of people thought: agreed The primary contributor to smoking's detrimental effects on the cardiovascular system is nicotine: disagree Mind linking to something that shows this? That doesn't agree with the results from the UK study on effects of nicotine versus smoking which puts nicotine's effects at about 5% of…

If you just look at what a pipe looks like if not cleaned properly, and picture the lungs looking the same, maybe the blood vessels too, then nicotene seems like the least of the problems. However, confounding factors means that a simple additive measure cannot illuminate the problem.

Short breath alone, which invariably follows the exposure to aggressive gases, leads to contraction of the vessels and increased heart rate, to keep up the oxygen level in vital parts.

Even if tar should not enter the blood streem in a healthy tester, which I'm not sure, the built up tar pits so to speak are cozy breeding grounds for all kinds of pathogens. Excess water in the lungs, or vice versa dry lungs impact the imunosystem as well.

You can test this yourself. Test your blood pressure prior to vaping and then after. If you choose to ignore all else you could argue the rise in BP is transient and not concerning. I personally would not bet my life on it.

Interesting so if my BP crashes I should smoke or vape :-)

I have had a BP crash I was cooking the Christmas dinner (the full works ) and accidently forgot I had taken my bp pills that morning and took a second set.

I passed out and vomited about 10 mins after sitting down to eat

If you believe E-Cigs are harmless, there's an easy experiment you can do for yourself. Go on a run, time yourself. The next day, vape for 30 min and then go on the same run. This is what got me to personally switch away from E-Cigs. Vaping would add an additional 30-sec to 1-min per mile on my runs. I try to only use patches or gum now. Still not great but it's a lot better if you're trying to stay in shape. That be…

Are most people in the type of shape that 30 seconds per mile variance day to day is surprising? I don't time myself, but I'd be surprised if any two of my sprints aren't this different normally.

This is definitely a point which needs more exploring. Seems to me most damage from smoking is all the crap in smoking. The chemical nicotine - by itself - transiently raises BP, feels nice, and that's about it. It's also only a part of the addictiveness of smoking. Probably a small part, as everyone I know who has consumed nicotine in any form has no trouble without it if they vape, but often shows discomfort/restle…

Is there any research on what other chemicals might be addictive?

Jogging in place will also transiently raise your blood pressure.

Indeed, too much training can be counter productive. Vice versa, runners can't just stop and settle down, neither after a race nor after a carreer, or they'd risk heart failure. I cannot explain it but I think it's common knowledge.
