I am flying into Cancun from the US in 2 weeks. Any issues from Mexican customs arriving or security departing Cancun? Everything will be in my carry on. 3 small mods, batteries separate in a case, 4 tanks, coils, charging cords, eliquid. I went through Mexico City twice last year but just in transit and had no problems. I think it is illegal to import for sale but this is personal use. I know I won't have issues departing/arriving the US - have done that many times. Thanks for any insights.
