if someone searched the boxes.... then they were obviously looking for something, BUT if you don't hae anything growing at the address it was shipped to, what could there really be to worry about? i doubt they're going to send some undercover to follow you around and see where you take the shit.... so i'd say you're safe for the timebeing... i'm just wondering why they would search the boxes... if it was just the delivery company, that's against the law, atleast in the states, tampering with mail is a federal offense....
