Feds Make Biggest Pot Bust in History $12M worth of marijuana confiscated on Mexican border By Matt Cantor, Newser User Posted Jan 24, 2013 7:02 AM CST 80 comments Comments Border agents have seized a reported record amount of marijuana. (AP Photo/Ted S. Warren) (Newser) – The good news: US border agents have seized some 14,151 pounds of marijuana—thought to be the biggest seizure in history, the Los Angeles Times reports. The humorously depressing news: The 26-year-old man busted with the pot was betting he could just drive some 600 bales of it across the US border in a tractor-trailer. Agents at the border crossing in Nogales, Ariz., seized the pot, worth some $12 million, last week. The driver is being investigated by immigration and customs authorities. The previous record seizure: 12,000 pounds, at the same spot in 2010.
