Over the past few months, I have given some talks about public policies that could reduce the extraordinary number of Americans who are in state or federal prison. The audiences in every case were blessedly bright and engaged. Yet they also had a broadly shared misunderstanding about how two drugs are related to the U.S. rate of imprisonment.
At each talk an audience member expressed the view that over-incarceration would drastically diminish soon because states were now legalizing marijuana. I responded by asking everyone present to shout out their estimate of what proportion of people currently in a state or federal prison were serving time for a marijuana-related offense. The modal answer across audiences was around one third, which explains the shocked looks that greeted my pointing out that even under the most liberal possible definition of a marijuana-linked incarceration (e.g., counting a marijuana trafficker with 10 other felony convictions as being in prison solely due to marijuana’s illegality), perhaps 1% of the U.S. prison population would be so classified.
Not wanting to discourage people, I said that there was a different drug that was responsible for many times as many imprisonments as marijuana and for which we could implement much better public policies. I then asked people to guess which drug it was. Give it a try yourself (answer after the jump). Continue reading “The Link Between Overcrowded Prisons and a Certain Drug”
