British Columbia has a vital, "growth" industry, and they're rushing the product to market in the US. The Vancouver Sun reports: U.S. border officials say they have experienced a phenomenal increase in the amount of marijuana being smuggled from B.C. into the U.S. with commercial vehicles. The trend has become so pronounced that some 67 per cent of the marijuana found entering the U.S. at major B.C. land crossings now is in commercial vehicles. It's the basic economic principles of risk and return on investment that are driving smugglers to use the cover and carrying capacity of commercial traffic to increase the payload of each shipment of contraband, said Mike Milne of the U.S. customs and border protection department. "It's just profit; if you are going to take a risk or a chance at smuggling, it's go big or stay home," said Milne.
