After reading this, I guess I've been lucky that family and friends have been supportive of my changeover from cigarettes to vaping. They actually buy vape stuff for me for gifts. As already pointed out throughout this thread, the best way of addressing that type of argument is to simply point the person towards educational material so they can learn for themselves about vaping and harm reduction. If they still insist it's bad after that, well, you can't force folks to believe the earth is round when they're convinced it's flat.
