I'd recommend a bicycle helmet everywhere you go, and special signs for your street so people will drive slow. Seriously I can't fathom why anyone in this age would voluntarily start smoking, let alone someone apparently allergic to nicotine.
On-topic though: E-cigs are great for the simple reason that they apparently let you smoke them in hospitals because there's no open flame?
if a hospital knew what you were doing they would probably tell you to stop, not really understanding that its completely safe and the vapor is used in hospital inhalers anyway, minus the nicotine and flavor, lol. But yes you can vape on an airplane or wherever if you 'stealth vape', i.e. hold in the vapor until there is nothing visible to exhale and hide it in your hand a little. I stealth vape in movie theaters, airplanes, etc. all the time. I've heard of people blowing huge cloud of vapor on airplanes and what not and getting all uppity when told to put it away.. people like that suck so don't do that, managers of a private business can legally tell you to stop doing whatever they don't like that you are doing, or leave.
anyway to the guy who doesn't smoke - I wouldn't suggest you voluntarily get addicted to nicotine, no way. These are mostly for cig smokers who don't want to inhale burning tobacco and all the 4,000 chemicals that comes with it. While you can get 0-nicotine liquid for e-cigs, I don't sell any currently. This is useful for vapers who are ready to quit nicotine altogether but still need a 'crutch'. Myself and many others are perfectly happy to continue on vaping nicotine for the forseeable future.
