Even if you're not among the 63 percent of Americans who drink coffee every day, caffeine is hard to avoid. It's all over your corner store, from energy drinks to colas and bottles of iced tea to cans of Starbucks "Refreshers." For a while there, it was looking like even your gum was going to be caffeinated.
I wouldn't be surprised if caffeine were found to be harmful. Let's say that it's found to cause health problems, or to be responsible for specific instances of environmental degradation; would caffeine be attacked like tobacco?
