Border Patrol agents found almost four tons of weed hidden inside a shipment of jalapeños Thursday.

The shipment was going from Mexico to the U.S., according to CNN.

The driver was flagged for a secondary inspection at the Otay Mesa border into California.

A K-9 team was used during the inspection, and alerted officers about the peppers, according to a press release from U.S. Customs and Border Protection.

Inside the pallets of peppers officers found over 300 green packages that field-tested for marijuana.
