Well now they have those new machines, not just the X-ray but the deal that looks through your clothes.......I always opt-out of walking through it which gets me a very intimate search. They even rub their hand across your crotch pretty hard, and stick their fingers between your skin and waste of your clothes, sliding their hand around your waste line so if anything was being held by the elastic it would fall to the ground.
I've always been extremely paranoid when traveling with herb and have never had a problem until the new scanners. I've been too nervous to walk through one with herb anywhere on my body.......
My secure way of traveling requires a giant skin colored bandage, it's a giant rectangle about 5" long, 3" wide. I wrap up the herb in a tight ball with plastic wrap, multiple layers, then tape it to where my shaft meets my nuts, then cover it all up with the giant skin colored bandage. If anything it looks like I have a stiffy or overly large nut sack, but it has never let me down...Even opting out of the new machine's and getting an intimate rub down hasn't been a problem, only concern is to make sure when they rub your crotch with the back of their hand you don't hear crinkling plastic...
I think putting some joints in a cigarette pack or loose rolling tobacco pouch is a good alternative, but the nut stash is the safest imo. I had a lighter in a cigarette pack, and was "randomly" selected for additional screening, the guy just picked up the pack and shook it, then put it back in the bag, when I got through I was like oh shit there's a lighter in the pack.
I've accidentally left a metal bowl in my bag and they didn't stop me.
Buying herb at your destination is not always available....I got ripped off in hawaii by natives, and I had a hell of a time finding any even in LA since I didn't know the area at all. No way in hell I'd be able to find any on the east coast where people can't be open about selling herb. At least here in Seattle you can google "buy pot seattle" and have some within 15 minutes.
