British narcotics controls did not begin with American pressure after the First World War. The discussion traces a longer sequence through the 1912 Hague Opium Convention, wartime restrictions on sales to troops, and the Dangerous Drugs Act 1920. American advocacy supplied an international platform and coincided with a strong prohibition movement, but it did not give Washington automatic control over European policy. The example distinguishes inspiration and soft power from enforcement, especially when reform was already under way.
