“The policies the United States has had for the last 41 years have become irrelevant,” said Morris Panner, a former counternarcotics prosecutor in New York and at the American Embassy in Colombia, who is now an adviser at Harvard’s Kennedy School of Government. “The United States was worried about shipments of cocaine and heroin for years, but whether those policies worked or not doesn’t matter because they are now worried about Americans using prescription drugs.
