An allegedly religious organization called "Daniel Chapter One" (DCO) sells dietary supplements which they say help to prevent cancer
"DCO never claimed their supplements were FDA approved or that their use was supported by any oncologist, including the FTC’s paid expert. DCO, which is organized as a religious nonprofit corporation, has consistently promoted their dietary supplements as part of their “Christian spiritual and physical wellness ministry.” You may say that’s just a cover, but I don’t see how anyone — and certainly not the FTC — can objectively determine which religious messages are false, given that all religions rely on things that cannot be empirically proven.
The FTC’s case at trial rested on the belief that speech regarding the health benefits of any product is per se illegal unless it is supported by an FDA clinical trial. The FTC is thus trying to expand the FDA’s authority, without constitutional or congressional consent, to cover products, like dietary supplements, that are not within the FDA’s congressionally defined jurisdiction.
Making any speech illegal until a government agency approves it is a VERY slippery slope.
