Study suggests e-cigarette flavorings may pose heart risk
Article reports that laboratory tests on "cells that normally line healthy human blood vessels" using six different e cigarette flavorings concluded that "Vaping and some flavorings, even without nicotine, triggered blood vessel dysfunction that can increase the risk of heart disease..."
Apparently they found that cinnamon and menthol flavors were the "most toxic".
I have seen enough articles and "propaganda" against Electronic cigarettes, and about %95 of them are totally bogus. I studied hard when I first started vaping. Back then, everything was new, and I thought vaping was just a different way of delivering tobacco. I thought it was more about the Blu lights and looking cool, and I never thought of giving it a second look. That mentality went on for years. It was too expensive for me to just buy it on a whim. While pumping gas one night, I noticed an add for one of those "cigalikes", and the entire kit was $20... that much, I could buy on a whim.
That kit never did get me to quit, but it did open my eyes... I was smoking less because of it, and it tasted "ok" (which is a far cry better than a regular cigarette). I was determined to find something wrong with vaping, since I thought it was what the cool kids did. Sure enough, I found all sorts of articles about how bad it was, and everything, but the tone of all those articles seemed to come from a health elitist point of view, and focused on eating vegetables and drinking more water, etc... They all sounded the same as "sodas are bad, and should be banned as well as high fructose corn syrup." etc.... It all sounded jaded. Sure enough, the deeper I delved, the more I discovered the truth.... vaping is much better than smoking. But like with soda, chips, hamburgers, apple pie, etc.... they're not %100 safe. And that's how every report has come down to so far.... Vaping is not safe, but it is a lot safer.
So, depending on where you are at in your research, if you're a vaper, you'll be interested in it, and will do a bunch of research to come to the same conclusion... the media is jaded and biased. They're quick on the trigger on publishing eye catching danger articles, and there is little or no factual basis or comparisons. If you're new to the research train, then I ask you to do this to each article.... find the source(s) of the articles and see how credible that research is. more often than not, the article is based on another article... and it can be several articles before you get to the actual study, and then you'll find that study is either majorly flawed, or over 20 years old.
Ok, for argument sake, I will take your article.... It mentioned a study where they grew cells in a pitri dish and then subjected it to the flavorings. After tracking down Dr. Joseph Wu mentioned in the article, I noticed he
hasn't published anything relating to electronic cigarettes. the article does go into a slight detail about how they grow cells in a pitri dish and then expose it to flavorings, and blood from someone who has just vaped. It doesn't, however, mention the quantity of chemicals. It simply says that the cells were inflamed which might cause damage.... Again, no smoking gun. I will wait for his study to be published before I can comment further on it, but I can almost guarantee, they over saturate the dish with an enormously high amount of chemicals until they get the result they are looking for. Most of the time this is done through funding by the FDA. So, in order to get funding from the FDA, they have to show something that may cause harm.. in other words, If they find that ecigarettes are generally safe, they won't get paid. I'll wait for the published result.
