To be clear I just wanted the sale of an electronic cigarette not be tied to the sale of tobacco. I don't believe it would be in the public's interest to say, “where tobacco is sold is the only place you can sell electronic cigarettes“.
The electronic cigarette, or vaporizer, comes in two forms. One is disposable. It's a self-sealed thing. You use it until it runs out and you throw it away. Those are the ones you see sold at gas stations. They require absolutely no information. You just open it, you pull off the peel, and you can start using it. For the more sophisticated vaporizers—selling them in pharmacies, Walmart, Target, places like that—it's going to be an economic failure because they do require instructions to use, so you need motivated staff. You need time.
Leaving that type of product in a pharmacy is probably not going to financially do well for the pharmacist. The disposable e-cigarette, which is just a plastic tube, the simplest thing, may be perfectly fine.
