There might be soon:No doubt. But the FDA's actions seem clear in this regard. They seem to be moving towards formalizing a policy that defines them as drug delivery devices, subject to FDA approval and regulation. I think it's a mistake on their part, but it's going to be a fight to keep them from being classified in that way.
Absolutely. The juice is the issue for sure. There's no way to avoid having it classified as a drug... since it is a drug. By the same token, caffeine is a drug too, and there's no significant FDA regulation going on with it.

In addition to considering these eight factors, the Select Committee views with concern the continued addition of caffeine to cola-type beverages, representing as it does a unique addition to food of a pharmacologically active central nervous system stimulant. The amount of caffeine consumed as cola type beverages borders on the dose known to produce central nervous system stimulation in animals and man. Whether such stimulation constitutes an adverse effect or whether a potential hazard may exist for the segment of the population, particularly children, that is exposed chronically to stimulating doses of caffeine, cannot be answered on the basis of the evidence now available. Despite the long history of use and absence of definitive evidence of toxicity in mammalian in vivo test systems, there is a possibility that behavioral effects in children from the consumption of caffeine from infancy through adolescence exist, even though these potential effects are neither adequately documents nor are their consequences clear. The Select Committe is well aware that caffeine in cola-type beverages is not the only dietary source of this substance. However, based on the evidence available in May 1978, the Committee believes it is not appropriate to continue to consider caffeine as a generally recognized as safe substance for addition to cola-type beverages.
