I live in Amsterdam and I know other people (other people!!!) who send weed regularly to the states..
What THEY use are vacuum sealers and Vaseline.. Just vacuum the weed once, clean it preferably with alcohol, then vacuum it again, put Vaseline or Vicks on it, then vacuum it once more.
Use a box, don't pay extra fast delivery charges, just send.. you'll pay like 14 euros and it always comes to your address.
This is the most important part!!! Use a different name on your package but ofcourse send it to your address..
If caught.. you'll have to show why you deserve the Academy award for best actor and it should be all fine.. (just convince them why it can't be yours..) no way it is!!!
And they'll actually have to let you go eventually.
