Depends on whether its overseas or domestic. If domestic, there's a very small chance of getting caught unless the person who packaged it did so in a haphazard fashion. If it's international, you have to worry about customs. Customs does open packages because that's their job. They are opening more packages after 9/11. Most packages still get through customs but the risk is still much higher than in domestic deliveries. There are two main scenarios if a package gets seized. In the best scenario, all you will get an empty package and a seizure letter from customs if you have a package seized. Your address will then be flagged in the customs database--watch your back. Worst case scenario, the feds come knocking and bust you for a controlled delivery. It would all depend on the quantity and how busy law enforcement is at any one time (they're resources are too limited resources to go after everyone especially in big cities). Just some food for thought, a 19 year old friend of mine was busted for a controlled delivery and he's still in the slammer. That was 5 years ago.
