Science writer and journalist Simon Singh, who faces a libel suit from the British Chiropractic Association (BCA) for writing that a number of chiropractic claims of treatment of disorders unrelated to the spinal cord such as asthma were “bogus” has written in his column that it will be the last. He is resigning his job in order to give the libel suit the BCA has served on him full attention.

I recently pointed out an extensive review of the evidence for and against chiropractic treatment that showed that the claims that Singh objected as unsupported, are unsupported.
Another survey of the research literature for chiropractic treatments, that of Ernst (available free from the British Medical Journal), has an extensive collection of follow-on letters. The author, replying to the early letters, points out that neither his article nor the libel case are about safety; in moving onto safety in his reply, he concludes: “Applying the precautionary principle, one should therefore not recommend chiropractic but warn patients not to use this form of therapy.”
Surely any sincere business would respond by simply pointing to evidence backing their original claims. Not so the BCA. The BCA was offered an opportunity to write a rebuttal in the Guardian (the newspaper that published Singh’s original article), but declined, seemingly preferring to legally bludgeon the writer, rather than reaffirm readers of the accuracy of their claims and the validity of the particular chiropractic practices referred to. (Or withdraw them.)

Actually they have something in them, obviously. Apparently, it’s often sugar.
