A main benefit of electronic cigarettes is that they can used in places where smoking is banned, like bars, restaurants, offices. But for those who need a regular nicotine fix, the chance to smoke in planes — where stepping outside isn’t an option — is a big problem. You can’t smoke e-cigarettes in airplanes. At least not in planes operated by large American or European carriers. So, the only best solution for smokers in the air is nicotine gum and patches.
