The only official DEA source I can find for the fact that coca leaf extract is still used to make Coca Cola is the museum page on coca: https://museum.dea.gov/exhibits/online-exhibits/cannabis-coca-and-poppy-natures-addictive-plants/coca https://museum.dea.gov/exhibits/online-exhibits/cannabis-coc... The funny thing is that the slideshow at the bottom of the page gives anyone with even a limited knowledge of alkali extraction (like DMT acid-base) everything they need to know about extracting cocaine.
