3,300 pounds of marijuana seized at Mexico-San Diego border crossing

SAN DIEGO — Customs officials say they’ve seized more than one-and-a-half tons of marijuana inside a big-rig truck that was trying to smuggle the pot from Mexico into Southern California.

Customs and Border Protection agents say a tractor-trailer pulled up at the Otay Mesa cargo facility in San Diego on Nov. 19 supposedly carrying a shipment of lockers.

Also this week: Seventy-year-old Mexican man caught smuggling $1.4 million of pot into U.S.

But imaging equipment and a drug-detecting dog indicated the rig might be carrying something else.

Sure enough, authorities say a search of the trailer turned up 140 packages of pot weighing more than 3,300 pounds.

The truck was seized and the driver, a Mexican citizen, was turned over to Homeland Security investigators.

The new cannabis lexicon: Do you know the difference between shatter and wax? Fatties and pinners? We’ve got all the lingo, from A-Z.
