I travel to Mexico every 6 months or so, last time was a few weeks ago Feb 2017 with flying into the Cancun airport. The time before that was in Aug 2016, and they were confiscating e-cig gear, with getting mine through with no issues but was asked if I had any with me, I said NO! The law in Mexico is that you can not import into the country or sell any e-cigs in Mexico. Now on my past trip I was Not asked if I had any. I think now they realize we are bringing them in for personal use not importing but then again it all depends on who you get, and if the light turns red for you they will examine the inside of your bags. Here is what I do to avoid all this even if they examine my bags. I put my juices with no labels on bottles in my check in bag at a cost of $25 under 50 lbs, and put extra coils, with putting a extra tank or RBA in one of my toiletry bags mixed in with other junk razors, toothbrush etc. You can put the charger in any bag, check in or carry on. Two mods, one tank, one unlabeled bottle of juice I keep in my carry on or on me until I get to US screening TSA When you go through TSA screening leaving from the US take the tank or RBA off, and put in a quart plastic zip lock bag along with your bottle of juice. You are only allowed one quart bag in a carry on bag. And for your batteries they MUST be in PROTECTIVE CASES in your Carry On bag ONLY, NOT ALLOWED in the check on bag. Now after you pass the US TSA screening take your mods, juice, and tank, and keep on them YOU, put in your pockets a MUST. Once arrived in Mexico you Do Not get searched or go though any body x-ray, only your bags may get searched if the light turns red for you. Hope this helps, and have a great trip. PS When I travel anywhere taking a plane I bring two internal battery mods so no need for bats, and chargers just a USB cable, and wall wart.
