no its not dude, there was an artical about these guys getting busted for dealing, and this one guy talked about 3oz js. They moved 40 tons from canada to the us, through a tunnel over the boarder/boats with the weed incased in zinc and dragged behind the boats. if the coast guard came, theyd cut the lines, zinc would make it sink. after 6 hours, the zinc would dissolve, and they'd collect their shit.
intense.
