If you're drinking Mexican Coca-Cola made with cane sugar, then you're in America. Domestic Mexican Coca-Cola is made with corn sugar.
Americans are the only people dumb enough to specifically avoid "corn syrup shit" in their soft drinks.
The only Coca-Cola made with cane sugar, other than the specific "natural" stuff with the green label (which is US market exclusive, btw), is Coca-Cola made in Mexico for export to the US, because there is a market of uneducated idiots in the United States who think that drinking 52 grams of sugar is better for you than the equivalent in corn syrup. These are the same idiot Americans who have a heart attack at the idea of anyone lighting a cigarette but smoke three bowls full of carcinogens each day and like posts on facebook claiming it cures cancer.
Corn syrup isn't any worse for you than any other type of excessive refined sugar. 52 grams of refined sugar is horrendous for you in any form. Corn syrup is of course a problem because due to the US farm bill it's incredibly cheap, so manufacturers of processed foods add it to

ing everything. It's a problem because it's more prevalent, not because it's any more unhealthy. People who are particularly stupid will read that paragraph and the take-away for them will be "oh I see if I want to be healthy I should buy Mexican coke!" *facepalm*
The largest market for soft drink in the United States, by the way, is bottled water and seltzer water beverages like La Croix, containing no sugar in any form, as well as no sweeteners, and no artificial flavoring. Your comment is about a decade and a half late.
