I am looking for that other angle. As a caretaker for disabled persons, the ADA comes to mind frequently but if someone has another suggestion I am open to listening.
I would suggest ACLU.
Though can't say I would strongly suggest this, just a consideration. I'm thinking if you are doing something that is not-smoking and feeling harassed and/or told if you want to use your device, you have to go where smokers are, that ACLU would find that very interesting, and possibly want to fight it, along with you.
