i'll say it again, the best way is to put it in your underwear. wear boxer briefs and stick it under your nuts. if there are dogs involved tho you are fucked. there's no way to hide the smell from them. sorry.
I doubt the xrays would be able to tell that your bottle of basil or parsley was not really basil or parsley, but the dogs might. I wouldn't risk it, just buy some herb in italy.
I used to live in boston, flew in logan alot and yeah dogs aren't around early unless on weekends normally. You'll be fine taping it on your gooch aslong as you don't get random searched
Amen Brother, I have a buddy who has worked w/ drug sniffing dogs b4 & I haven't taken him up on the offer yet, but he's said he'll prove 2 me that a dog w/ smell the smallest amount of weed through the most amount of things. He said he's seen dogs smell like barely a few grams through like fucking steel & concrete & stuff. The only thing that can distract them is if you have a cat w/ you (which I'm pretty sure u can't do with an international flight unless you're moving or something) So yeah, if they have dogs who you get close enough to and they're trained to sniff it they'll fucking smell it & start barking.
