I’m not arguing that vaping isn’t massively better than smoking, but harmless? That’s a high bar. Edit: you’re correct about my irresponsibility, I apologize and have edited my post.
But you were replying to my comment questioning the outrageous claim that smoking's chief risk is cardiovascular disease caused by nicotine. You replied with only a link to a journal article, which could easily, at a glance, appear to back up that claim, although upon further reading, it certainly does not.
Do you see how that's kind of irresponsible?
