Done !
So guys ...there is no issue moving across USA airports with a small amount of kava then ??
I know I can get my 2 kg back into Australia no issues at all..done it many times.
I've brought kava on around six domestic flights and they've never even so much as double checked my carry-on. I had even loaded up GourmetHawaiianKava.com up on my phone, expecting to have to explain the mysterious bags of powder in my bag.
I would recommend putting it in your carry-on, though. If someone's suspicious, it would be better if you were present to set them straight instead of them throwing it away (or if they know what it is, stealing it).
And don't forget to bring a small spoon! You gotta have a way to get your root in a bottle of $10 airport juice.
