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 while 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." Ethical Beginning in 2006, as the result of his commercial ventures, Weil—as David Gumpert has described—has placed himself in the "awkward position of ... having to defend himself against charges of inappropriately exploiting his medical-celebrity status." 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, the DrWeil.com personalized service of recommending supplements (purchase of which are made easy via DrWeil.com and drugstore.com), long-standing recommendations for supplements appearing despite studies questioning their efficacy, and to the clear nature of the pressures on Weil because of the deals, and the clear consanguinity of person and brand. The Forbes article noted, in particular, drugstore.com's 2005 lawsuit against DrWeil.com for Weil's having "failed to perform any of his marketing obligations", noting that in a 2004 Larry King Live interview, Weil failed to promote this business partner, despite the program offering "reasonable opportunity for Weil to use efforts to promote drugstore.com." Moreover, the CSPI's newsletter noted that their investigations into the vitamin and supplement recommendation service led them to conclude that the algorithms behind the recommendations were, by default, set to recommend purchases: regardless of how the online inquiries of the personalized service were answered, "we couldn't get the Advisor to stop recommending that we buy supplements." The CSPI article concludes, "Beware of doctors who sell what they recommend." In 2006,
