Medical Medical professionals in particular have criticized Weil for promoting treatment claims and
alternative medicine practices described as unverified or inefficacious, or for otherwise rejecting aspects of
evidence-based medicine. Weil's rejection of some aspects of
evidence-based medicine and his promotion of
alternative medicine practices that are not verifiably efficacious were criticized in a 1998
New Republic piece by
Arnold S. Relman, emeritus editor-in-chief of
The New England Journal of Medicine and emeritus professor of medicine at Harvard Medical School. The late
Barry Beyerstein of
Simon Fraser University, writing in the journal
Academic Medicine in 2001, criticized Weil and various aspects of complementary and alternative medicine, asserting that it held a "magical world-view"; he continued, saying,In 2003,
Steven Knope, author of
The Body/Mind Connection (2000), a physician trained at
Weill Cornell Medical College, and former Chair of the Department of Medicine in the Tucson, Arizona, Carondelet system, criticized Weil in a televised discussion for what he considered irresponsible advocacy of untested treatments.
Simon Singh, a recognized British science writer, and
Edzard Ernst, a former Professor of Complementary Medicine at the University of Exeter, echoed Beyerstein's criticism in their 2008 book
Trick or Treatment, saying that although Weil correctly promotes exercise and smoke-free lifestyles "much of his advice is nonsense."
Social Hans Baer of the Department of Sociology and Anthropology at the
University of Arkansas, writing in 2003, has argued that Weil's approach represents a general limitation of the holistic health/New Age movement, in its "tendenc[y] to downplay the role of social, structural, and environmental factors in the etiology of disease" in the United States, and in doing so, represents a failure to "suggest substantive remedies for improving access to health care," generally, for the "millions of people who lack any type of health insurance"; at the same time, Baer notes (with negative connotations) that Weil instead contributes "to a long tradition of entrepreneurialism in the U.S. medical system." Commenting on a cover article in a recent 2006 edition of the
Center for Science in the Public Interest's "highly respected"
Nutrition Action Healthletter, Gumpert called attention to: • a $14 million deal Weil's business enterprise had made with
drugstore.com, where he emphasized the benefits of
fish oil supplements without a disclaimer that he had a direct commercial interest in the sale of these supplements. Another specific criticism has been leveled with regard to the message of his
Healthy Aging (2005), which argues that aging should be accepted as a natural stage in life, while these skin care products were being sold at
Macy's with the advertising claim of the products' "optimiz[ing] skin's defense against aging"—alongside a large picture of Weil. Weil has also been accused by others in the alternative health movement of being involved in the "dishonest practice of spreading
fear, uncertainty, and doubt about competitors' products, while pretending to be [an] objective 3rd [party]."
Political Weil's 1983
Chocolate to Morphine roused the ire of Florida senator
Paula Hawkins, "who demanded that the book, a veritable encyclopaedia of various drugs and their effects on humans, be removed from schools and libraries." ==Formal corrective actions==
