Sanho Tree is a Fellow at the Institute for Policy Studies and has been Director of its Drug Policy Project since 1998. A former military and diplomatic historian, his current work encompasses the reform of both international and domestic drug policies by promoting alternatives to the failed prohibitionist model. In recent years the project has focused on ending the damage caused by the drug wars in Colombia, Bolivia, Mexico, Afghanistan, and the Philippines. Establishing humane and sustainable alternatives to the drug war fits into the IPS mandate as one of the major contemporary social justice issues at home and abroad.
