I respect anyone's differing opinion, but I don't want a prescription for this at all. Keep it where anybody can get it, and not have to wait a month of so for an appointment. If cigarettes don't need a prescription, as much as they can affect a person's health, why subject an innocent e-cig to that? That could give people the impression that they can't use the stuff without a doctor's discretion, which IMO sends the wrong message about these things.
I want the c-stores, nightclubs, military, Walmarts, Wendy's, airlines, and any other entity to have vending machines and/or over-the-counter sales for this. People should be able to use these things in absolutely any public establishment, just as long as they can confirm that they use vaporless e-cigs. There may even be requirements, like movie theatres with food, that you not bring in your own refreshments, but you can consume as many of their own as you want. The imagination runs wild, when you think about how businesses will permit the use of these things on their premises.
