E-Cigarettes With Nicotine Increase Your Risk of Heart Disease, Says Study (theverge.com)
An anonymous reader quotes a report from The Verge: Even after puffing on just one electronic cigarette with nicotine, healthy non-smokers were found to have a biological marker known to increase the risk of heart disease in tobacco users, according to a new study. The research, published in Journal of the American Heart Association, shows that nicotine is not harmless, as many people believe. It can affect a smoker's health in more than one way, and not just by triggering addiction. Another study, conducted by Middlekauff that was published earlier this year, showed that people who use e-cigs almost every day have biological markers known to increase the risk of heart disease in tobacco users. These included an increase in adrenaline levels in the heart, which can predispose smokers to bad heart rhythms, heart attacks, and sudden death, as well as increased oxidative stress, an imbalance in the body's ability to defend itself against the damaging action of free radicals. Oxidative stress can lead to changes in blood fats and lead to arteriosclerosis.
That study, however, didn't show what exactly was causing those changes. E-cigarettes can have different flavoring and solvents, as well as nicotine. So to identify the culprit, Middlekauff brought 33 healthy non-smokers and non-vapers into the lab. On three different days, one month apart, the participants were asked to puff on three different kinds of e-cigarettes for 30 minutes: one with nicotine, one without nicotine, and a sham e-cig that was empty. The researchers did blood tests and measured the subjects' heart rhythms, and found that the participants had high levels of adrenaline in their hearts after they smoked the e-cig with nicotine, but not after they puffed on the e-cigarette without nicotine or the empty e-cig.

E-Cigarettes With Nicotine Increase Your Risk of Heart Disease
I'm shocked! SHOCKED I TELL YOU!
But I'll bet there's a hell of a lot less tar!
If you want news from today, you have to come back tomorrow.
Consuming a stimulant causes stimulant effects.
is an indicator of a state or situation. For example c-reactive protein (one of the substances mentioned in the paper) is a marker of inflammation. It's actual function is to signal the immune system to clear out dead cells (both our own and bacterial).
Ischemic heart disease is an inflammatory disease; therefore if you are developing ischemic heart disease, you will find high levels of inflammatory markers like C-reactive protein.
However it seems to me it's a bit of a logical leap to do something which transiently increases inflammatory markers and then assume that means the subject's chances of getting a specific inflammatory disease are increased. Maybe I'm misunderstanding the paper.
Post may contain irony: discontinue use if experiencing mood swings, nausea or elevated blood pressure.
One of the markers was increased adrenaline. As in the stuff that helps athletes perform their best. So no ecigs, no exercise, got it.
But as for the rest, some people who would otherwise keep smoking will use ecigs instead. Some who would start smoking will use ecigs instead. That's bad how?
As for helping you quit, ecigs helped me quit. After a number of years vaping, I found that I just wasn't interested in the nicotine anymore. No drama, no nail biting, no eating the entire refrigerator, nothing. Just no more interest in nicotine.
That's the part that really hacks them off, I sinned by smoking and they want to see some serious suffering as penance.

Seriously? This is supposed to be impressive, useful science or something? So people who don't use nicotine consumed it and had typical, known, short-term heart rate changes after using that stimulant? And since none had any tolerance, the reaction was probably strong, right?
Now repeat that experiment with people who don't use caffeine and have them consume that stimulant instead and measure heart rates and heart adrenaline levels. Wow, what a coincidence!
Why the broadside to vaping? Surely this study extends to nicotine gum, nicotine patches, and nicotine sprays as well.
Compare ecigs to tobacco when looking at the health issue since the overwhelming majority of ecig users are former smokers.
At the moment.
The trouble is, two different questions are getting conflated here: (1) Are e-cigs safe? and (2) Are e-cigs safer than tobacco? The latter is pretty much a no brainer - and e-cigs are clearly great for people trying to quit smoking.
However, claims for safety in absolute terms seem to rely a lot on an "absence of evidence is evidence of absence" mentality. If e-cigs are touted as "harmless fun" rather than "a good way to quit" then, increasingly, non-smokers and, ex-smokers who have successfully quit are going to take it up, and existing vapers are going to vape more freely than they used to smoke. In 20 years time we'll find what continually inhaling glycol and assorted flavourings does to lungs, let alone what ever-increasing doses of nicotine does to you if lung cancer doesn't get you first.
That shit you cooked for dinner last night for dinner was far more offensive.
Yes, well, the increasing number of people who turn up to work with tupperware containers full of stinky food that they proceed to microwave in the office kitchen (previously reserved for cups of tea and the occasional celebratory cake) until the whole corridor is filled with the miasma from 57 varieties of re-heated leftovers are on my shit list too :-)
BTW - what do you think happens to all that glycol, glycerine and flavouring (which you might not use but plenty of other vapers do) after you breathe it out in a confined space (esp. in a bar with 30 other people doing the same)? The fact that the "smoke" disappears rapidly just means that the droplets have got too small to see. When you're banned from smoking in your own, freehold, detached, single-occupancy house, then maybe I'll side with you - in the meantime, if you want to vaporize chemicals, fuck off outside where others don't have to breathe the results. If you're addicted to nicotine you'll rationalise any sort of antisocial behaviour to satisfy your craving, which is why we need laws.
