Sure I have. Smoking kills. And vaping is ultimately just as safe as the nicotine patch. It doesn't take much to understand that.
But as long as you are entertained mocking me by posting smarmy pictures, enjoy. I find it despicable. I doubt you ever research the topic. But the WHO, the World Health Organization, can be accused to killing millions with their zealotry that pushed many countries to outright ban vaping, while smoking remains perfectly legal and convenient. That is the result of many fraudulent studies.
This is not a trivial topic about "an axe to grind". From my perspective, it's not much different than mass murder. Why? Because of stupidity or profiteering.
So laugh it up. Mock me if you want. I don't have time or energy to read and debunk this latest study, they are relentless. But I have read these kind of studies in the past and all the anti-vaping studies turned out to be fraudulent. Fraud use for propaganda leading to bad policies and preventable deaths. That is the moral dimension of this shit.
