There’s so many layers to this. First, there’s history: Coka-cola (originally made from a Kola nut and cocaine) was told they couldn’t put cocaine in their “medicine” anymore so they just sold it as a “soft-drink” without the cocaine.

Then there’s the beverage industry who pointed out there’s caffeine in tea leaves and other plant material and that it’s not a threat: (1) US vs 40 barrels and 20 kegs of Coka-cola. Ultimately reducing the amount of caffeine in soft-drinks.

Round and round we go allowing companies to use chemicals to keep us buying their consumables.
