Guess I will be finding a different layover spot if doing any international travel. Typically this is one of the main layover hubs after a 14-hour flight from the US. In the past you would have to go
through customs and exit the airport to smoke and then when you came back in have to go
through customs again.
I can see how this new law may catch a few unaware travelers off guard and possibly in hot water if traveling with
vape gear in their carry on (since you cannot put in your checked luggage either). Thanks for the info!
