Yeah. Orange juice concentrate. And the cocaine was in bags. Boring.
But this is interesting: Coca-Cola was originally considered an "intellectual beverage." But when it started coming out in bottles:
Anyone with a nickel, black or white, could now drink the cocaine-infused beverage. Middle-class whites worried that soft drinks were contributing to what they saw as exploding cocaine use among African-Americans. Southern newspapers reported that "negro cocaine fiends" were raping white women, the police powerless to stop them. By 1903, [then-manager of Coca-Cola Asa Griggs] Candler had bowed to white fears (and a wave of anti-narcotics legislation), removing the cocaine and adding more sugar and caffeine.
