Not the boats for this study (though they may help in the future ).

From the article:

“About 70% of American overdose deaths are caused by fentanyl, a synthetic opioid. Networks shift, but currently most American street fentanyl starts as building-block chemicals produced in China. Those are shipped to Mexico, where drug gangs formulate them into fentanyl and smuggle it across the border.”

The stronger border is optimistically placing more control of the problem in US hands.
