The U.S. 'Pure' Food and Drug Act of 1906 did not ban coca, nor even mention it. But would treat it unfairly via requiring labeling of cocaine content (with no such requirement for caffeine and nicotine containing substances), and allowing the USDA to define something as “adulterated” for containing whatever the USDA could declare to be a dangerous, habit-forming or deleterious (with no requirement that any such declaration be grounded in consistent science).US Pharmacopeia - Wikipedia
The 1906 act would effectively exempt Tobacco via its definition of USDA authority over drugs as confined to those listed in the US Pharmacopeia.
Tobacco was included in this Pharmacopeia until being dropped in 1905.
