side effects, and their efficacy, Weil advocates for the use of whole plants as a less problematic approach in comparison to synthetic pharmaceuticals. In addition, Weil is an advocate of incorporating specific medicinal mushrooms into one's diet. Weil has expressed opposition to the war on drugs, and takes a measured, nuanced approach to the use of recreational drugs. Publications Overview While Weil's early books and publications primarily explored altered states of consciousness, he has since expanded the scope of his work to encompass healthy lifestyles and health care in general. In the last ten years, Weil has focused much of his work on the health concerns of older people. In his book Healthy Aging, Weil looks at the process of growing older from a physical, social, and cross-cultural perspective, and in his book Why our Health Matters is focused on health care reform. Of his books, several have appeared on various bestseller lists, both as hardbacks and as paperbacks (many appearing so in the 1990s), some of them being Spontaneous Healing (1995; on the New York Times list), Eight Weeks to Optimum Health (1997; on the Publishers Weekly and New York Times lists), Eating Well for Optimum Health (2000; Publishers Weekly, New York Times), The Healthy Kitchen (2002, with chef Rosie Daley; New York Times), Healthy Aging (2005; New York Times), and Spontaneous Happiness (2011; New York Times).
