The American Medical Association's opposition to chiropractic was at its strongest in the 1940s under the leadership of Morris Fishbein. Fishbein called chiropractors "rabid dogs" and referred to them as "playful and cute, but killers" He tried to portray chiropractors as members of an unscientific cult who cared about nothing but taking their patients' money. Up to the late 1970s and early 1980s, the medical establishment purposely conspired to try to destroy the profession of chiropractic. In fact, a landmark lawsuit in the Supreme Court of Illinois in the 1980s found that the American Medical Association was guilty of conspiracy and was ordered to pay restitution to the chiropractic profession.
In the 20 years since, the opinion of most medical doctors has changed: several major studies have shown the superiority of chiropractic in helping people with a host of conditions, and medical doctors developed a better understanding as to what chiropractors actually do. Many people have returned to their medical doctors and told them about the great results they experienced at their chiropractors office. Hospitals across the country now have chiropractors on staff, and many chiropractic offices have medical doctors on staff. Chiropractors and medical doctors are now much more comfortable working together in cases where medical care is necessary as an adjunct to chiropractic care.
