President Donald Trump's plan to impose tariffs on goods from Mexico, Canada and China is partly aimed at combating the illicit flow of fentanyl into the U.S., where the opioid is blamed for some 70,000 overdose deaths annually.

“A 25% tariff on Canada and Mexico threatens to upend the very supply chains that have made U.S. manufacturing more competitive globally,” he warned, adding that the “ripple effects” of Trump’s tariffs would be especially severe for small and medium-sized manufacturers that may struggle more to find alternative suppliers.
