Sodas contain: caffeine, charcoal, mineral oil, tar, refined sucrose, carbon dioxide.
Diet sodas contain: caffeine, charcoal, mineral oil, refined sucrose, carbon dioxide and artificial sweeteners which are made either from petrol(saccharine, cyclamate) or methanol(aspartame).
Why the fuck would anyone put this into their bodies is beyond me. I can understand using coffee, alcohol or nicotine because these things give pleasure, but why would anyone drink pure poison is beyond me. If it is the caffeine from sodas you want, then coffee or tea gives you the same without any of the poisons.
The stories about aspartame and other sweeteners causing brain damage and cancer are exagerated: the body can deal with pretty much any momentary poison without sequelae. But taking this shit every day, day after day, for years, cannot be good for you. It just can't.
