16. British House of Lords – Nov 28/00 Science experts in Britain's House of Lords called Tuesday for tougher regulation of alternative medicines, saying many practices offered no evidence of helping the ill. Peers in parliament's upper chamber said there was also a risk that patients would pursue alternative therapies at the expense of traditional treatment, endangering their health. ``One of the main dangers of complementary and alternative medicine (CAM) is that patients could miss out on conventional medical diagnosis and treatment because they choose only to consult a CAM practitioner,'' the Lords’ science and technology committee said in a report.

17. Canadian Disbelief The goverment of Canada moves into the realm of woo woo medicine as it funds the Office of Natural Health Products. It's about to fund $100 million research institute to study alternative medicine in Hamilton, Ontario. Without the support of organized medicine, and the government, much of alternative medicine would be considered quackery and fraud. The derogation of the responsibility of science based medicine and their cooperation with pseudo-science based health gurus is a big mistake. Canadian medicine is hurting, our hospitals are starving for support and our patients are dying in ambulances in our major cities because our government funds alternative medicine. ~ Alt Med Newswatch, Dec 30/00
