As Arlo Guthrie put it, “You know, if one person, just one person does it they may think he’s really sick,” but if enough people do it, “friends they may thinks it’s a movement.” – from Alice’s Restaurant. The critical mass theory applies to vaping, although on a smaller scale. I have been vaping at work for over a year and a half and have helped a few people switch to e-cigs. Lately, a co-worker in the same building started vaping and became the catalyst for a chain reaction of a half-dozen now former smokers. Nice. And it has really got me thinking that as this alternative to smoking grows at an exponential pace, it will be harder and harder for the antis to stop it. Let’s hope so.
