I am not sure totally how the marijuana trade is handled on our border with Canada, but smuggling is taken seriously down here. (Heavy fines and stiff jail sentences.) Drug smugglers use every means possible to get it into the States, from just carrying it to using specially built submarines. I also have no idea who in official places would like to see the decriminalization of marijuana especially so it could be taxed. The only thing it would accomplish would be destroying its monetary value, the smugglers and growers would just grow something else.
