Just wondering if you guys do this outside or just in the home. I can see myself using this inside all of the time. I can see myself using it in my car as well. And in some situations I can see myself using it outside where a normal smoker would. But has anyone really tried to use this indoors where it isn't widely understood what it is? I'm curious what the reactions would be, and I'm not sure I would feel comfortable using this in some situations, but I have nicotine gum for that.
