Heres my stand on all this......when i vape "Dry Herb" its in the privacy of my own property. i believe thats the responsable thing to do. i wouldn't fire up a joint in public..(Before the flaming starts I'm legal.) to be its a respect thing. even if nobody can tell. and as far as normal vaping goes if i do it in public i do it in smoking areas only. just because theres no smell does not mean i can do it where ever i please. just like, i Open carry. because its legal, however i also have my CCW. but I'm not that guy that open carries in Walmart. if that correlation makes sense
