I've done it a few times myself, my fav. method was taking a buy 2 get one free parliament pack, taking one pack out carefully taking the sulafane off the top, stuff the tree in ( sealed and all), put the salafane back on, and the pack back in, i brought like three of the deals so it looked good, put it in my check on bag...i think that was all before 9-11 though.....
Beginning of 08 i was in south africa and brought some seeds back no problem, i put them in a the spine of a postcard with a few others in a thin brown bag tehy came with and then put them in a book, when i got to NY i was 30sec from walking out the doors, liek 7 am after a 23 hr flight and this cop was like come here please, he made me empty out all my shit and put it all back, he was pretty chill though let me keep a wooden pipe (which was clean) but said he should have taken it, but didnt find the seeds
OK last story this summer i was in israel and smoked some hash...for some reason i put roach of it in a one of those little airborne medice things right on top and completely forgot about it...i had it in my carry on right in the front pocket of my backpack..ANyway the security in israel is pretty fucking intense, the most i've ever seen and they do it all right in front of you...everything went fine but i got home and found it like it a week later and almost shit myself...to top the story off i was currently awaiting a court date for a few weeks after i got back, when i get to court i my lawyer was like "don't worry its not your fault there was a computer error, but you had a warrant out for your arrest" i was like ohhhh great. so not only did i unknowingly bring a roach of hash back but i had a warrent out for my arrest. Can you say LUCKY
From now on i'm gonna have to go with the get it from where your going method, i was in LA in march and was a few days in dying for some smoke so was liek fuck it, went ot the guy outside who takes peoples bags, calls taxis, etc and was liek you got any tree?" 5 min later he came back with a gram of some really nice shit...
its nto worth bringing it on the plane with you, shit could always happen, no matter how safe you are...next time i might even try mailing it before i go, that sounds pretty safe, the trick is wait a while before opening it and right return to sender so if you do get busted be like idk what that is and they can't do shit, so i've heard.
Sorry fo rthe long post, i like tellign my stories, haha, hope you guys got somethign out of it
