It seems so, but not so by plane. Although it's not recommended in either case. Your taking a big chance, up to you.
well my friends have had some bad experiences carrying drugs on trains to belgium. like 4 out of 5 times they've done it theres been sniffer dogs on the train. and they all had a lot of dope and pills on them. they just dumped them in the toilets as soon as they saw them coming. but one got arrested. i dont know how he got out of that one though.... also i always bring a little stash home from amsterdam. its always highly stressful and im not sure if its worth it.
