After all, if vaping poses a greater risk of stroke than smoking, then there is absolutely no reason to quit smoking using e-cigarettes. You'd be better off smoking. And if you already quit smoking by switching to e-cigarettes, then you'd be better off returning to smoking than continuing to vape. Why take a chance of increasing your risk of suffering a stroke?
Uhm, because even if their conclusions are correct, which I doubt, stroke is by far not the only malady that smoking might cause.

Oh geez.

"E-cigarettes may pose the same or higher risk of stroke severity as tobacco smoke. ... Electronic cigarette (e-cigarettes) vaping may pose just as much or even higher risk as smoking tobacco for worsening a stroke, according to a preliminary study in mice presented at the American Heart Association's International Stroke Conference 2017. ... From a brain health perspective, researchers said, electronic-cigarette vaping is not safer than tobacco smoking, and may pose a similar, if not higher risk for stroke severity."

Shame on them. This is science????? :evil:

Best guess: they subjected the mice to dry-hit toxins at exposure levels that no human would experience in multiple lifetimes.

Burn the broccoli until it's black. Eat 100 of pounds of charcoal broccoli daily for decades. Unwanted results occur. Conclusion: broccoli is bad.

Nope. They delivered a large does of nicotine and artifically caused a stroke. Then compared recovery with a control group. The study is a duplicate of an earlier study expect for delivery method. This study used inhalation and the previous study used subcutaneous injection as the delivery method.

The AHA announcement fails to highlight the previous study. The two studies together provide evidence to the statement, no increased heart risk with vaping nicotine compared to using the patch.

If:
E-cigarettes may pose the same or higher risk of stroke severity as tobacco smoke

Then:
Steaming vegetables may pose the same or higher risk of stroke severity as tobacco smoke
Why do I not see this headline?
The nicotine contents of vegetables
Vegetable Nicotine in ng/g g per 1µg nicotine
Cauliflower 16.8 59.5
Eggplant (Aubergine) 100.0 10
Potatoes 7.1 140
Green tomatoes 42.8 23.4

Let's not try to debunk bad "science" with even worse stuff. Nic content of those vegetables in in the parts per billion (ng/g) while nic content of tobacco and vape juice is in the parts per thousand. That's a factor of a million difference in concentration.

Saw that mentioned on Plumes last night. Their study basically showed that a nicotine dose significantly above the LD50 caused bad things to happen to mice. Same would be true for caffeine, water, or cheese.

My analysis of this garbage:

Big Pharma/FDA/NIH funded American Heart Association press release falsely claims vaping may increase stroke risk more than smoking (based on totally inapplicable rodent study in which mice were given more than a lethal dose of nicotine daily for 30 days).
ISC17 Thursday News Tips | American Heart Association

Unfortunately, the lazy stupid news media repeated AHA's false fear mongering claim without any fact checking.
