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…

I ride a bicycle daily and vape e-cigs. If anything I notice an increased performance immediately after vaping, I feel like I'm less tired and have more energy. Overall this is an interesting topic because contrary to popular opinion many athletes use nicotine and find that it increases their performance: Nicotine [...] use is widespread amongst professional team/strength sports (e.g. American football, ice hockey, w…

Yeah, I never said I quit nicotine. Just switched to mostly gum.

It seems as if you were trying to maximize your performance, you'll ingest nicotine in a way that doesn't go through your lungs.

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…

I've been a long-time smoker, and at least for me, nicotine alone does absolutely nothing to alleviate cravings. Gum, patches, lozenges, vaping, etc. do zero to alleviate my craving for a cigarette. I'm not discounting that nicotine is addictive (I'm in no position to say), but there's got to be something else in tobacco that is part of the addiction.

It takes willpower. Believe in yourself, draw a line in the sand, you're no longer smoking real cigarettes. Stick with it. You're the one in control of your actions.

I readily buy their conclusions, but this really should be placebo controlled.

MRIs are loud and obnoxious and upleasant. If you told me that this result (observed on MRI#2) was entirely the consequence of having done MRI#1, I would find it plausible.

Those athletes have trained for years and have a heart that is well conditioned with strength and cardio. A normal person who is moderately physically active is nowhere near their fitness level. That’s why nicotine is a dangerous thing to gamble with. You might be fine, or you might have afib/vfib that leads to an MI. Rather avoid the risk. Plenty of more potent PEDs out there that don’t cause adverse cardiac events.

Many people seem to believe that vaping is harmless, this is good to make the point clearly that vaping, while not as harmful as smoking cigarettes, isn't a "cost free" activity. I personally didn't realize that it could have these effects either.

My main concern with the way things are going is that it looks an awful lot like attacks on vaping are for the purpose of driving smokers back to cigarettes. I know of no one that things vaping is harmless. It is certainly much, much less harmful than cigarettes and is infinitely preferable to cigarettes. I quit smoking, with the help of vaping. I was a pack-a-day Newport smoker that started on a ludicrously high 36m…

> There is a theory in the vaping community, or maybe its an urban myth, that the lack of MAO inhibitors is what allows people who vape to essentially lose their addiction.

Definitely a myth, I never smoked but vaped for 2 years. I quit a few months ago because I was vaping so much I noticed some pretty bad side effects, the increase in blood pressure was real. Nicotine is highly addictive, I still feel like I want to do it and it takes willpower not to go back to it.

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…

I'm not an expert, but my understanding is its not at all clear enough to make such a strong, simplistic statement. For example:

Are there any similar studies for marijuana vapor inhalation?

But the likelihood is that vaping is order of magnitudes less harmful than smoking burning cigarettes, but the way narrative is being spun is that vaping is a grave danger to health.

Normal cigarettes have established to be undisputedly harmful, whereas ecigs while possibly addictive, the long term effects of consumption are merely not well known/studied.

Despite any studies, I would be very interested to hear a theoretical assessment of the safety of ecigs.

It's not hard to say it's better than smoking. Every study done to date comparing the two days it's not nearly as harmful as smoking. Smoking is one of the most harmful things you can possibly do to your body. Many people underestimate how much of a low bar being better than smoking is.

That seems like a foolish argument. The time horizon in which we discovered smoking was bad for you was decades, and over a massive population of users. E-Cigarettes are only now becoming mainstream, and have only been in use for the better half of a decade. We wont truly know the effects until we have a large sample size over a long period of time. Ultimately, saying it's conclusively better for you than smoking is…

You seem to think that science do not have the ability to predict the effects from causes, it is possible to say if vaping is safer than normal cigarettes now itself, rather than have to wait for 50 years to make that declaration. Theoreticaly ecigs are much much safer, due to the lack of combustion and presence of carcinogenic smoke components.
