Is it really possible for a caffeine free diet coke to have caffeine in the future? That sounds nonsensical.<|im_end|>
<|im_start|>assistant
You're right, it certainly does sound nonsensical on face value. However, when it comes to advertising and marketing a product, there are different rules and regulations for what is allowed to be said. Sometimes something can be marketed as caffeine free so long as it is below some minimum threshold. Changes to the ingredients in the future may have an impact on the actual quantity. If you find that you need absolute certainty it is best to check Coca-Cola's website as they'll have the most up to date and accurate information for your needs.<|im_end|>
