Why then do the airlines prohibit me from using my personal vaporizer (aka, e-cigarette) on their planes? It is my drug of choice and creates a cloud of vapor that smells like strawberry, but most people don't care if they smell a faint strawberry smell. The guy sitting next to me drinking coffee puts out as much smell as my PV, but I'd go to jail.
My theory is that it *gasp* looks like smoking. Can't have anything that even looks like it might offend someone. Catering to the lowest common denominator has gotten us nowhere.
