A friend showed me this message in her inbox: FYI: The new coke zero contains ASPARTAME which is know to be carcinogenic or cancerous. And FYI, cancer is now the leading cause of death worldwide. So don't drink Coke Zero. And always be a label reader. Please forward to your family and friends. What do you make of it? is this just a smear campaign? I haven't actually read the label of coke zero though i have drunk it a few times.
