This is why they'll never get rid of pot.

That my friends, is a bona fide maryjane catapault.Parrently the smugglers were using it to launch their stuff over the border into the States. At this point I'm going to say that trying to bust drug operation is quite the waste of time. If the dudes you are trying to bust are inventive enough to come up with a $50 buck solution to a problem you spent several mil to create, then it's time to throw in the towel. It would honestly be twice as devastating to just legalize weed, as then people would have legit sources, there'd be competition, and you could tax the snot out of it. Or you could make more fences, and add a marijuana laser interception system. (Note: nobody steal that idea. Gonna sell it to the americans.)
