I keep my headphones, my earbuds, my lightning chargers, my wall plugs in my Pax Era vape pen with the charging cord attached to it all in a clump in my carry-on bag. The Pax vape batteries are rectangular and very inconspicuous, especially when attached to a power cord sitting in amongst all the other electronic stuff
I throw the little resin pod in my dopp kit with the razor, toothbrush, etc.
I’ve carried that exact vape pen for three years all over the country to Mexico several times and a couple times to Europe. I’ve never so much has had anyone look in my bag.
Even though I’m going through the clear TSA pre-line I keep a gallon freezer bag with all the little 3 ounce lotions and mouthwash so that’s the first thing anyone would see.
I prefer my vape pen to buy marijuana at one of the cigar places on Hidalgo. Were they always take me aside and ask if I want marijuana.
I’m pretty sure they know that if they start busting people for a joint then the number of Americans will go down there will drop - and they want our money.
