Well last year while on our family vacation to maine we took a plane..of course me not knowing any dodgy Dealers down there i brought my 14 gram stash. Now i've heard of it and decide to try this. I took freshly ground cofee beans and had about a full ziploc bag full of them with that i then took my baggies of 1 gram and shoved it in there..incredebly i got threw :). So if your ever wanting to smuggle > cofee will do it.
