Chopra taught at the medical schools of Tufts University, Boston University and Harvard University, and became Chief of Staff at the New England Memorial Hospital (NEMH) (later known as the Boston Regional Medical Center) in Stoneham, Massachusetts, before establishing a private practice in Boston in endocrinology.  While visiting New Delhi in 1981, he met the physician Brihaspati Dev Triguna, head of the Indian Council for Ayurvedic Medicine, whose advice prompted him to begin investigating Ayurvedic practices. Chopra was "drinking black coffee by the hour and smoking at least a pack of cigarettes a day". He took up Transcendental Meditation to help him stop; as of 2006 he continued to meditate for two hours every morning and half an hour in the evening.  Chopra's involvement with TM led to a meeting, in 1985, with the leader of the TM movement, Maharishi Mahesh Yogi, who asked him to establish an Ayurvedic health center. He left his position at the NEMH. Chopra said that one of the reasons he left was his disenchantment at having to prescribe too many drugs: "[W]hen all you do is prescribe medication, you start to feel like a legalized drug pusher. That doesn't mean that all prescriptions are useless, but it is true that 80 percent of all drugs prescribed today are of optional or marginal benefit."  He became the founding president of the American Association of Ayurvedic Medicine, one of the founders of Maharishi Ayur-Veda Products International, and medical director of the Maharishi Ayur-Veda Health Center in Lancaster, Massachusetts. The center charged between $2,850 and $3,950 a week for Ayurvedic cleansing rituals such as massages, enemas and oil baths; TM lessons cost an additional $1,000. Celebrity patients included Elizabeth Taylor. Chopra also became one of the TM movement's spokespersons. In 1989 the Maharishi awarded him the title "Dhanvantari of Heaven and Earth" (Dhanvantari is the Hindu physician to the gods). That year Chopra's Quantum Healing: Exploring the Frontiers of Mind/Body Medicine was published, followed by Perfect Health: The Complete Mind/Body Guide (1990).
