Add Triplicate States?

[Predict-This]

Hello! Relatively simple and powerful addition to this resource would be to add a shapefile or simple dataset of Triplicate States. See https://academic.oup.com/qje/article-abstract/137/2/1139/6427381?redirectedFrom=fulltext&login=true for the powerful contribution of this program to prescription deterrence. "We find that OxyContin distribution was more than 50% lower in “triplicate states” in the years after OxyContin's launch."

This sounds reasonable! Will start process of data sourcing for this.
