there are ways of 'smuggling' i personal think hash is easier.

the type of person customs pick on:

someone in untidy clothes
a guy with long hair
a guy who's unshaven
someone carring a guitar
drunk or very stoned(coming from A'dam)

so if your any of the above DO NOT smuggle, DO NOT smuggle more than 10g you could be put in prison, under 10g they take the dope away, give you a large fine and the airline you were flying with will not allow you to fly with them. there's a lot of risk involved.

i like the combination of shampoo,plastic sandwich bag and condoms best(yes there is something else useful for a pack of three).
as i said hash is easier, roll/compress the hash into a sort of pencil shape, place it into the sandwich bag and wrap the bag around it, now place this inside a condom and tie(with as little air in the condom as possible) a knot at the end, do the same for the other two condoms, place this into shampoo.

as your shampoo is in a bag with your other toiletries the x-ray machine will just see a jumble of shapes.

it's worked for me in the past, although since airport security has been getting so tight i haven't tryed for about 5 years.
