I openly vape at home, in my car, in bars, outdoor eating areas of restaurants, and outdoors in general, (at 25-30W with a 0.9 ohm ccell coil when in public). I sometimes stealth vape, (lower wattage, tighter draw, hold before exhale), in places like grocery stores, movie theaters, etc. Regardless, I don't vape obnoxiously by blowing clouds or exhaling vapor toward anyone.
I've never had a problem, but this is AZ, and people in general here are more respectful of personal liberties than in most other states. Ymmv.
