They seem to be just playing with statistics. A majority of States are red or leaning red as they point out, so naturally, a wide study like this will show a majority of most things in red or leaning red states.
This is typical of how sensationalistic clickbait news usually works. They take to unrelated facts, try to make a connection, then make a conspiracy with a catchy headline like a fishing lure. To somehow jump to this being an Obama conspiracy against Red States is asinine.
A better correlation to look at is the states with the highest rates of disability payments. The greater the percentage of those on disability, the likelihood they will be on some sort of pain medication. The more on pain medication, the greater chance they are on opioid medications which have this risk.
