UK homeopathy controversy rages on. In February, The House of Commons Science and Technology Committee issued a 275-page report that examines the British Government's policies on providing homeopathy through the National Health Service (NHS) and the licensing of homeopathic products by the Medicines and Healthcare products Regulatory Agency (MHRA). [House of Commons Science and Technology Committee. Evidence Check 2: Homeopathy. Feb 8, 2010 ] The report debunks many of homeopathy's common claims and places homeopathic research in proper perspective. It concludes:

In July, the UK Department of Health issued a response which acknowledged that "the evidence of efficacy and the scientific basis of homeopathy is highly questionable" but the products should remain available "to provide patient choice." [Secretary of State For Health. Government Response to the Science and Technology Committee report 'Evidence Check 2: Homeopathy'. July 2010]

Professor Michael Baum, one of the leaders of the scientific community's effort to de-legitimize homeopathy in the UK, expressed astonishment about this decision. in a comment in The Lancet, he stated:

Using this kind of logic, why not offer astrology on the NHS to help women decide when to induce labour? It beggars belief that a modern NHS that prides itself on evidence-based medicine should fly in the face of the Science and Technology Committee, which concluded that homeopathy is nothing other than an elaborate placebo and involves deceiving the patient every time it is prescribed. [Baum M. Homeopathy waives the rules. The Lancet 376:577, 2010]

Evidence Check 2: Homeopathy is one of the most insightful reports on homeopathy ever published. The full text is available online.

Chiropractic attrition rate examined. A newly published study has found that the 10-year attrition rate for California chiropractors rose from 10% for graduates licensed in 1970 to a peak of 27.8% in 1991 and remained between 20% and 25% from 1992 through 1998. The study was done by examining data from the California Department of Consumer affairs to see how many chiropractors held active licenses ten years after their initial licensure. The reasons for license loss include a move to another license jurisdiction, personal illness or disability, employment in other professions/jobs, disciplinary action against the license for improper behavior, retirement and death. The authors believe that the attrition rate is related to a drop in the number of potential patients per chiropractor causing a drop in income. [Foreman SM. Stahl MJ. The attrition rate of licensed chiropractors in California: an exploratory ecological investigation of time-trend data. Chiropractic & Osteopathy 18:24, 2010] The American Chiropractic Association has estimated that the average (mean) net income for all chiropractors in 2000 was $81,500, which was $5,000 less than the comparable figure for 1996 and $20,000 less than the comparable figure for 1989. U.S. government census figures indicate that between 1992 and 2007, reported income from chiropractic clinics nationwide rose from $5.9 million to $10.0 billion. Since the number of chiropractors has increased and these numbers are not adjusted for inflation, they show that the individual chiropractic income in terms of real dollars has dropped sharply. These findings add to the evidence that many students who enter the field of chiropractic will be unable to earn a living.
