I think that’s what their saying, since coke/cocaine and coke/coca cola are both named coke because of the same chemical.

I dunno which came first tho, far as I can tell cocaine in both drug and drink form started getting called coke around 1900-1910. The coca-cola company didn’t like the nickname, they advertised you saying the name in full, they didn’t actually copyright “coke” for coca-cola it till the 1940’s.
