when i was a kid (14-16 year old) i would travel with my parents often to other countries like italy, mexico, canada, france, etc...i can't tell you how many cuban cigars, absinthe, pot, and other contraband i smuggled back to the US without any problems. I just put everything in my big luggage and checked it. i feel like there's minimal security for checked luggage.
i'm not saying it will work 100% of the time, i realize i was young and stupid, but i'd say the odds are in your favor of not getting caught if you just put it in your checked luggage. depend on what the consequences are and if you're willing to risk it.
either way, good luck! let us know what you decide to do and how it works out.
