For the third episode of Periphery, co-host/co-producer Angelika Albaldejo and I spoke with Sanho Tree, the director of the drug policy project at the Institute for Policy Studies. We talked with Sanho about the history of drugs and the drug war, both in the U.S. and abroad.

Sanho is one of the top experts in the drug policy field and his unconventional professional background gives him a unique perspective on these issues. We are really grateful that we got to speak with him and even more grateful that we get to share our interview with our audience.
