The House dove Tuesday, Tuesday, June 12, 2018, into a two-week vote-a-thon on dozens of bills aimed at opioid abuse, as lawmakers try to tackle a crisis that’s killing tens of thousands a year and to score a popular win they can tout for the midterm elections. A handful of the measures are contentious, including one Republican bill that would create new criminal penalties for making or trafficking certain synthetic drugs containing fentanyl.
