Border agents say new trend is putting children at risk.
Federal agents in charge of monitoring drug smuggling along the U.S.-Mexico border say more and more teenagers are getting involved in the smuggling trade - and may even be at risk for recruitment.
According to federal agents, many suspected teen smugglers have been caught this year at the San Ysidro border trying to cross into the U.S. with drugs secretly taped to their bodies.
Agents say both American and Mexican children as young as 12 years old are being recruited by cartels as drug mules. And, these days, marijuana is no longer the drug of choice.
