My sister has one of those blood pressure meters that measure your heart rate at the same time. When she was still smoking, she always had to wait for about half an hour after a smoke before measuring because the cigarettes would make the blood pressure and heart rate go way up. She's tested it with vaping, even when she vapes at the same time she's measuring, there's no change in either blood pressure or heart rate.
That concurs with other reports I've read in the past, where studies were done looking at how the cells of the heart react when people smoke and when people vape. With smoking the heart cells immediately go into stress, vaping didn't cause any stress whatsoever.
If one of the major brands they've used was the vuze, you should well remember that thing contains 48 mg/ml of nicotine and probably a lot of chemicals too.
For the rest I don't really care what all these so called studies are saying, especially when you look at the stuff they are peddling and are calling safe, as long as there is a huge profit attached to it.
I know how I felt when I was a smoker and I know how I feel right now and that's all the study I need. If it wasn't for vaping, I would still be smoking today. Is it completely safe? Probably not, neither is the air we are breathing everyday. I don't really see them scrambling to improve the air quality out of concern for our safety. Too much profit going on in pollution.
Everything they deem unsafe, like cigarettes, is heavily taxed, so called to discourage further use. They know damn well an addict will pay whatever it takes to get a fix. They just want to put vaping into the same category as smoking so they can put the same amount of tax on it.
Why isn't there a war on nicotine patches and gum if nicotine is such a disastrous and harmful drug? I can pick them up in every drugstore and they are at floor level, you know, easy to reach for the little ones they're so concerned about.
