Although there’s no evidence of any significant flows of fentanyl into the United States from Canada, an American authority on “criminal supply chains” warned Friday that that could change abruptly if U.S. efforts to better seal its border with Mexico are successful.
Jonathan Caulkins, who researches supply chains that support illegal markets for the Manhattan Institute think tank and Carnegie Mellon University. said the drug cartels that control the North American fentanyl trade may well shift large chunks of their operations to Canada if the northern border becomes the path of least resistance.
