my boss just back from a trip said he vaped discretely on the plane right at his seat. sent the vaporizer with his carry on baggage.
I got my bag searched when I went on a trip by doing this. As soon as it went through the x-ray machine at the airport TSA pulled me over and asked me to open my bag. Then he looked at me funny and I vaped in front of him, he just sat there and said... "OH OK?!" I guess he thought it might be a pipe bomb, damn mods lol.
