Growing up in Ohio and Pennsylvania we called soft drinks "pop." In Cleveland we bought a local pop called " Little Tom." My favorite chocolate syrup to put in milk was Bosco. One of my favorite places to go when I was a kid was an A&W root beer stand for a root beer float.
The actual original coca-cola had cocaine in it. They finally removed it in 1929 from what I've read. My father told me his father was "hooked" on Coca-Cola, drinking several a day. He died in 1934 at age 55.
Around here, all soft drinks are cokes or co-colers. Some of the older folks when I was a kid called them sody waters or sody dopes, or just dopes. I think that might have originated with the cocaine in the original Coke formula.
