I spent a solid half hour discussing the mixer possibilities of the cinna-coke tonight, despite never actually seeing one in the wild. I’m intrigued if nothing else.
Greasy E, the local dreadlocked white guy drug dealer around here, has been adding cinnamon to his coke for years. It's his trademark.
To me the effect is similar to coke-flavored Teddy Grahams. It's good but I think Pepsi Fire was better.
