I always fly, and I always just keep the hash in my pocket, or occasionally down my pants. Having said that, I'm an innocent looking fella, so I never get stopped anyway. I also don't worry about it, so don't give myself away sweating about it. I only ever bring back a half Oz at a time though...nowadays.
I also took some mdma through singapore airport on a transfer on my way to Thailand once....That was a slightly damp moment though I have to say. I'm not sure I'd risk that again.
I've got a few stories I guess. Once brought weed from Lao to Thailand and had an argument with the head of the border (a guy in a proper communist style military outfit) because I didn't want to pay a fine for overstaying my visa. Obviously they never thought to search my bag, what moron would start a fight over $20 if they had an ounce of sensi in their backpack
Was amazing weed though, and only cost like $1 for the small carrier bag full. Weed was basically free in Lao in 2000!!
Sometimes a bit of front help. Got me out of time in a cell in Thailand (without having to pay a hefty bribe either!) when I got collared while skinning up at a full moon party!! Fucking close call that one!!
I've never had close calls like that bringing stuff though uk airports.
