FTC issues homeopathic advertising guidelines. The Federal Trade Commission has announced a new policy toward homeopathic product advertising. The agency also released its staff report on its 2015 workshop. Homeopathy, which dates back to the 1700s, is based on the medically disputed notion that disease symptoms can be treated by repeatedly diluted doses of substances that supposedly produce similar symptoms when provided in larger doses to healthy people. Many homeopathic products are diluted to such an extent that they no longer contain even a single molecule of the initial substance. The policy statement notes:

The marketplace would be more efficient if product labels and ads would list only ingredients and include no efficacy claims, as recommended by Dr. Stephen Barrett. [Barrett S. Comments and proposed testimony for the FTC workshop on advertising for over-the-counter (OTC) homeopathic products. July 29, 2015] But the FTC appears willing to permit efficacy claims accompanied by "sufficient" negative disclosures.


Canadian court authorizes class-action suit against chiropractors. The Quebec Superior Court has authorized a class-action suit to proceed against 13 chiropractors and their insurers. The plaintiffs were treated for back pain at Zero Gravity clinics with a spinal decompression machine called the Axiom DRX 9000. The company went bankrupt in 2013, but the suit is directed against the individual chiropractors: Yves Bélanger, Marc Bureau, Amelie Jean, Bertrand Canuel, Patrick Fortier, Mario Amyot, Yoland Guimond, Catherine Morin-Noiseux, Valérie Bouthillier, Giovanni Ippolito, Caroline Huot, Jean Theroux, and Marie-Noelle Side. All of the case documents are in French. The complaint (in French) and Google's English translation of the judge's ruling are available online. The complaint states:

The law firm handling the case is Ménard, Martin of Montreal. Press reports indicate that 650 people have signed up, but up to 8,000 people might be eligible. [650 people get permission to sue chiropractors. CTV News Montreal, Nov 23, 2016]

Spinal decompression is an expensive high-tech form of mechanical traction that can relieve some cases of back pain but has been widely promoted with unsubstantiated claims that it can correct degenerated and herniated discs without surgery.
