One of the sillier talking points in the Wall debate is that we need a physical barrier to keep opioids from coming into the country from Mexico. Various commenters have pointed out that: (1) The fentanyls, which are the fastest-growing segment of opioid use and overdose deaths, mostly come directly from China; and (2) What does come across the U.S./Mexico border comes through overwhelmingly by common carrier at ports of entry; it isn’t backpacked through the desert by immigrants.
A point I haven’t seen made, and didn’t know about until Kevin Drum posted this graph based on data from the CDC’s Morbidity and Mortality Weekly Report, is that the crisis isn’t concentrated anywhere near Mexico. All of the hardest-hit states in terms of opioid mortality rates are east of the Mississippi and north of the Tennessee, about as far as they could be from the Rio Grande. Of the four states that actually border Mexico, New Mexico and Arizona are in the middle of the pack, while California and Texas rank 45th and 47th.
So Trump’s Wall remains a solution in search of a problem.
