This video is of 30 tons of marijuana. It was seized by authorities from a single tunnel running under the Mexican-American border, near San Diego. This 30 tons, that is 60,000 pounds, is merely the amount of marijuana this single active tunnel had on hand. The total amount of marijuana that over time was moved through just this one tunnel was probably much higher.
Americans are going to keep using marijuana, and as long as it is illegal, violent criminal organizations are only going to keep finding new ways to make sure they make massive profits off of this illegal trade.
