every one here is telling you not to do it b/c they prob dont smoke but if u were talking to potheads they'd be like do it!!
it depends who you ask......... i would say someone with experience(not me)
i was thinking about it but didnt do it
but on my last cruise there were people smoking n they didnt get in trouble or arrested
my suggestion is think about the risk your taking......... you probably have to pass security, customs, and security again....... twice
if you think its worth it go head
