I dunno what everyone is so freaked about... I travel a lot and carry kush with me nearly everywhere I go, including across international borders.
I have brought 10gs into Finland...
I've even been tagged by a drug dog coming back from Amsterdam (where I obviously had no need to bring it with me), so I have a decent understanding of how it works.
IMO, the best way to conceal and bring herb with you on the plane is to simple take enough that will fit double bagged into a cigarette box. I rip out all of the aluminum to assure it will not beep in the metal detector and just keep it on my body.
My logic is this:
If its taped to you and you're approached, you are screwed.
If its hidden in your luggage and you're approached, you are also screwed.
With a pack of "cigarettes" in your pocket, if approached, you can toss it away.
I will often keep one cigarette in there so that if approached, I open it up, take out "the last cigarette" and toss the package, then pretend to make my way to the nearest smoking area.
The only way I feel comfortable is if I have the ability to ditch it at a moment's notice and have it look like garbage...
For example, took some hash from Denmark to Finland simply broken down and wrapped in paper chewing gum wrappers... carried them in my hand, under my passport when I got to Finland cuz if I saw a dog, I'd just drop it like most people drop gum wrappers...
