kouk DID at one time, back in the 1920's/1930's, have cocaine as an additive in it's product. In fact, kouk used to be used Medicinally back then. But people liked the taste so much, that soon they added carbonated water (for bubbles), and sold it at Soda Stands within stores. I believe it was in the 1950's when the FDA found Cocaine to be addictive, and made the Company take out the Cocaine property. The taste was still there, but the Cocaine was out!
And NO, it NO LONGER contains Cocaine! Trust me! But it would kinda be nice to have that when my body pain gets really bad! :/ But I still drink anyway... cus "Things go better with Coke!" ;D
