The border is the front line in the war on drugs. But the DEA says marijuana is still Mexico's biggest cash crop.
At the same time more U.S. states are making it legal.
There's medical marijuana, and Washington and Colorado now allow its recreational use.
Julian Leyzaola, the police chief of Juarez, said he hopes those states grow their own pot. Otherwise the marijuana they smoke will be stained with Mexican blood, Leyzaola said.
More than 60,000 people have died in the Mexican drug war since 2006.
Now that country's new president says he is ready to take another look at the policy as more U.S. states decriminalize the drug.
Of course, marijuana is not legal in the eyes of the federal government, and it's still banned in plenty of states, including Texas. But even in the Lone Star State some are changing their views.
"Twenty years ago you would have never convinced me that I'd be saying this today: Legalize drugs. Turn the American farmer loose on it and we will be the world's largest exporter," said farmer Jim Ed Miller.
The issue came up earlier this fall when we visited Jim Ed Miller on his farm. It's right on the border and smugglers were cutting across his land.
"Whether we can find a market, I don't know. But they ain't going to be sneaking it in here," he said.
But at least for now, smugglers will keep trying.
