If I'm throwing in my two cents, there is absolutely no way in hell that I'd risk it. I've traveled pretty extensively through south-east Asia, particularly Thailand, and you couldn't pay me to take flowers or concentrates through the country, let alone if you have to use airports.
For starters, the penalties are downright medieval level draconian. If you get caught, you will go to jail. Not just any jail, south-east Asia jail. South-east Asia jail is to American jail what hell is to heaven. You will have no legal recourse but to take what you're dealt by a system that wants to make an example out of foreigners.
So how likely are you to actually get caught? A lot more than you would traveling around the US. As others have said, if you look like a western foreigner who is there for travel, then you look like a way to make a quick buck. If you stick to tourist friendly spots then you should be ok, but head out of town and you may as well paint a sign on your head. You will be searched at every available opportunity, not because they suspect you of wrongdoing, but because they suspect that you have money. They want a bribe. If you have nothing on you to get you in trouble then it's probably worth your time to go through the whole routine and insist that you will be seeking legal recourse if they continue to hold you without giving a reason. At least that way it will only cost you your time. Your best bet is to have one of the more expensive local drivers to escort you around, constantly. You are far less likely to be bothered that way.
I was forced to miss a flight out of Thailand (the airline re-booked me for the next one but didn't cover any extra costs incurred by me) because of this. The excuse that they used was that one of the scans of my girlfriends luggage showed what, they claimed, appeared to be a magazine of bullets. It was very, VERY obviously a bracelet. They proceeded very, very slowly in moving towards a solution and gave me multiple hints and opportunities to find some "other way to deal with" the situation. I had been through enough searches at this point to realize what they were doing and that being at an international airport and not at some backwater bus station that if I stuck to my guns they'd have to let me go. Even after opening the luggage and handling the bracelet, they took it and STILL tried to stall as much as they could. I told one of the guys that I'd be there as long as I had to, that I knew they wanted money, and that the longer they made me wait, the closer I was to seeking legal help. That REALLY pissed the guy off and they eventually let us go, but not before our flight left.
If you absolutely HAVE to take something, go with the edibles hidden in a bag of other similar candies or something. As a fellow vaper who cares about others in the community, please, don't risk it.
