Our guest this week is Richard Auxier, senior policy associate at the Urban-Brookings Tax Policy Center. He will talk about the flurry of activity at the state level on marijuana decriminalization and legalization and lessons learned thus far on how to tax this economic activity.

This interview is part of TPC's series of online conversations on tax and fiscal policy in today’s economy. The discussions take place every other Thursday afternoon and feature varying perspectives on the historic economic challenges facing the United States and the world and the best ways to address them.
