Don't give up so easy my friend, from personal experience I can tell you that minds can be changed. Where I work there was a very negative opinion of vaping. As some here may know I keep a bit of printed data and used that information to educate my coworkers. Our facility went from a no vaping to us being allowed to vape in our office space. Being a little OCD I print information and keep it in my car, when the anti vaping conversation starts I quietly excuse myself and grab information from my car and rejoin the conversation. It's not enough to just talk the talk because people just believe you are spewing anecdotal information. When you place fact under their noses it makes the argument that much more difficult. Anyone that wants information on vaping and second hand exposure just shoot me an e-mail and I will either send you PDF's or links to information you can use. Knowledge is power!
